Bromodeoxyuridine (BrdU), a thymidine analogue, can be incorporated into the DNA of dividing cells and is widely used to label new cells.61-63 To label proliferating cells, BrdU (100 mg/kg) was injected i.p. daily starting at day 1 post TBI for 10 days. The number of BrdU-positive cells found in the ipsilateral cortex, DG, and CA3 areas was significantly increased 35 days after TBI compared with sham controls.18,34,64,65 Tβ4 treatment further increased the number of BrdU-positive cells compared to saline controls.34 The increased number of BrdU-positive cells may result from effects of Tβ4 on either increasing cell proliferation or reducing cell death of newborn cells. Our recent data show Tβ4 increases oligodendrocyte precursor cell proliferation and differentiation in animal models of stroke25 and experimental autoimmune encephalomyelitis.27 Tβ4 may not directly affect cell proliferation but inhibit cell death, for example, in corneal and conjunctival epithelial cells treated with benzalkonium chloride in vitro66 and endothelial precursor cells under serum deprivation.67 Our data further show that neurogenesis increases in TBI rats treated with Tβ4, suggesting that Tβ4 promotes newborn cells to differentiate into neurons. This is consistent with the effect of Tβ4 on promoting epicardium-derived progenitor cell differentiation into endothelial and smooth muscle cells to form the coronary vasculature.22 Whether the increased number of BrdU-positive cells in the brain of TBI rats treated with Tβ4 is tissue specific remains unknown. Tβ4 may not directly affect cell proliferation. Increased cell proliferation and neurogenesis are also possibly secondary to that Tβ4-mediated angiogenesis, as described later.
Hey mate, I’m getting a shoulder reconstrcution in about 2 weeks. Do you think that TB-500 and BPC-157 would help heal something as complex as this. Or do you think that stacking something like GHRP-6 and CJC-1295 would work better because this would assist in muscle growth and strength gains of surrounding muscles etc. Also if chose to use peptides when do you think I should start using them, I will be in a sling for 6weeks after surgery with only passive movements.

Autism: Oxytocin has been implicated in the etiology of autism, with one report suggesting autism is correlated with genomic deletion of the gene containing the oxytocin receptor gene (OXTR). Studies involving Caucasian and Finnish samples and Chinese Han families provide support for the relationship of OXTR with autism.[55][56] Autism may also be associated with an aberrant methylation of OXTR.[55]


Oxytocin is relatively safe when used at recommended doses. Potential side effects include: Central nervous system: Subarachnoid hemorrhage, seizures; Cardiovascular: Increased heart rate, blood pressure, systemic venous return, cardiac output, and arrhythmias;Genitourinary: Impaired uterine blood flow, pelvic hematoma, tetanic uterine contractions, uterine rupture, postpartum hemorrhage.

Why have zebrafish retained the ability to regenerate? It is thought that the capacity for organ regeneration is an ancestral condition that has occasionally been diminished in the course of vertebrate evolution (Scadding, 1977; Goss, 1992; Wagner and Misof, 1992). Thus, most biologists suspect that the molecular machinery to optimize regeneration is present but poorly-utilized in mammals. By this line of reasoning, zebrafish heart regeneration may represent an optimal utilization of universal cardiac machinery.


Thymosin beta 4 is a small 43 amino acid protein (a peptide) that was originally identified in calf thymus, an organ that is central in the development of immunity. Tb4 was later found in all cells except red blood cells. It is highest in blood platelets that are the first to enter injured areas, in wound healing. Tb4 is also detected outside cells, in blood plasma and in wound and blister fluids.
These studies demonstrate that in the animal model of TBI, early (6 hours post injury) treatment with Tβ4 i.p. at doses of 6 and 30 mg/kg reduces cortical lesion volume and hippocampal cell loss and improves functional recovery, suggesting its potential as a neuroprotective therapy for TBI. More importantly, delayed (24 hours post injury) treatment with Tβ4 administered i.p. at a dose of 6 mg/kg does not reduce lesion volume but significantly improves functional outcome in rats.34 Tβ4-induced angiogenesis, neurogenesis and oligodendrogenesis may contribute to functional recovery.34 Therefore, our data suggest that promoting endogenous neurorestorative processes using Tβ4 provides a novel therapeutic option for TBI. It should be noted that systemic administration of Tβ4 is safe and well-tolerated by animals and humans.26 Further investigation of the molecular mechanisms underlying Tβ4-mediated neuroprotection and neurorestoration is warranted.
Oxytocin produces antidepressant-like effects in animal models of depression,[81] and a deficit of it may be involved in the pathophysiology of depression in humans.[82] The antidepressant-like effects of oxytocin are not blocked by a selective antagonist of the oxytocin receptor, suggesting that these effects are not mediated by the oxytocin receptor.[17] In accordance, unlike oxytocin, the selective non-peptide oxytocin receptor agonist WAY-267,464 does not produce antidepressant-like effects, at least in the tail suspension test.[83] In contrast to WAY-267,464, carbetocin, a close analogue of oxytocin and peptide oxytocin receptor agonist, notably does produce antidepressant-like effects in animals.[83] As such, the antidepressant-like effects of oxytocin may be mediated by modulation of a different target, perhaps the vasopressin V1A receptor where oxytocin is known to weakly bind as an agonist.[84][85]

I was in a bad accident 5 years ago and was feeling better until my Dr. gave me levaquin which damages your mitochondria, gut, tendons And ligaments. I was going to order BPC 157 but see where you think TB500 is stronger. Do you know if it shows up on an employee drug test as i get tested occasionally? Also, your thoughts on fragment 176-191, a friend of mine uses it and suggested it for me. I understand you’re not a Dr, but just looking for your personal opinion. Thank you
I’ve been on this stuff for lots of years. I really needed it when I was depressed like hell, and I had an emotional pain that simply didn’t go away for 2 decades prior to starting that stack. Did it help? yes. Was it the best intervention possible? probably not. I was able to get off all this stuff with the uridine stack, and I believe it partly fixed a part of my brain that was damaged from this decade long suffering. So this is, why I am now more into brain regeneration and psychotherapeutic interventions (even though I do them myself), and I would only go back to this stack if I was completely fucked up again. There are a lot of side effects, and its a fine line to balance the supplements, to get rid of the side effects…
In the male mammal, the small peptide hormone oxytocin is produced in similar quantities within the hypothalamo-pituitary magnocellular system as in the female, yet for the male little is known about the physiology associated with this hormone. The present review summarizes what is known about the function of oxytocin in the male mammal and tries to take account of both central and systemic effects, and those linked with a local production of oxytocin within the male reproductive organs. In several species a pulse of systemic oxytocin, presumably of hypothalamic origin, appears to be associated with ejaculation. The systemic hormone could act peripherally stimulating smooth muscle cells of the male reproductive tract, but could also reflect central effects in the brain modulating sexual behaviour. In addition to systemic oxytocin, the peptide is also made locally within the testis, and possibly also the epididymis and prostate. In the former tissue it appears to have an autocrine/paracrine role modulating steroid metabolism, but may in addition be involved in contractility of the seminiferous tubules. However, the latter function may involve the mediacy of Sertoli cells which under some circumstances can also exhibit the components of a local oxytocin system. In the prostate of the rat and the dog oxytocin is linked again to steroid metabolism and may also act as a growth regulator. Finally, oxytocin in seminal fluid is discussed and its possible role in respect to the fate of the semen following ejaculation.
5-HTP supplements are made using an extract from the seeds of Griffonia simplicifolia,a tree native to Africa (2). 5-HTP very rarely occurs naturally in what we eat, but tryptophan, from which 5-HTP is made in the body, is found in a variety of foods. The richest natural food sources include cheese, poultry, eggs, fish, nuts, soy, and various greens.
Some differences in cardiac anatomy exist between mammals and teleosts. The zebrafish ventricle has a thin wall of compact muscle surrounding a much larger compartment of myofibers organized into elaborate trabeculae. It is intriguing that this structure is very similar to that of the embryonic mammalian ventricle prior to its septation and fusion of trabeculer myofibers into a thick, vascularized wall (Sedmera et al., 2000). That the mammalian heart has a more differentiated, contractile anatomy is apparent not only in gross cardiac structure, but also in cellular features. Teleost cardiomyocytes are 2–10 times smaller, mononucleated, have a greatly-reduced sarcoplasmic reticulum and lack the T-tubule system found in skeletal muscle and mammalian cardiac muscle (Farrell, 1992). One might speculate that the teleost heart is better designed for growth and regeneration, while the mammalian heart is better designed for sheer contractile force. Nevertheless, none of the mentioned differences between lower and higher vertebrate hearts preclude the idea that the mammalian heart could be stimulated to regenerate, especially if that regeneration is due to mobilization of a progenitor cell population.

What to know about hormonal imbalances While it is natural to experience hormonal imbalances at certain times in life, such as puberty, menopause, and pregnancy, some hormonal changes are related to underlying medical conditions. This article looks at the causes and symptoms of hormonal imbalances in men and women, as well as treatment and home remedies. Read now
The reason for the difference is the density of oxytocin receptors in the brain. Life pair bonders, like prairie voles or, indeed, ourselves, have a high density of receptors in the reward centre of the brain. Non-pair bonders, like meadow voles, certainly enjoy sex, but their lower density of receptors means it doesn't matter so much who the partner is. So it's not the oxytocin itself making sex enjoyable. What it's doing is influencing our mating behaviour.
Consult a health care practitioner if symptoms persist or worsen. Consult a health care practitioner prior to use: if you are pregnant or breastfeeding; if you are taking carbidopa or drugs/supplements with serotonergic activity including, but not limited to, L-tryptophan, S-adenosylmethionine (SAMe), St. John's Wort, antidepressants, pain killers, over-the-counter cough and cold medication containing dextromethorphan, anti-nausea medication and anti-migraine medication. Discontinue use and consult a health care practitioner if you show signs of weakness, oral ulcers, or abdominal pain accompanied by severe muscle pain. Do not use if you have scleroderma. Exercise caution if operating heavy machinery, driving a motor vehicle or involved in activities requiring mental alertness. Some people may experience diarrhea, nausea, vomiting, abdominal pain and drowsiness.

Once the baby is born, oxytocin promotes lactation by moving the milk into the breast. When the baby sucks at the mother's breast, oxytocin secretion causes the milk to release so the baby can feed. At the same time, oxytocin is released into the brain to stimulate further oxytocin production. Once the baby stops feeding, the production of the hormone stops until the next feeding.

Six hours later, the mice were returned to cages with the aggressive mice. The mice that were missing their oxytocin receptors didn't appear to remember the aggressive mice and show any fear. Conversely, when mice with increased numbers of oxytocin receptors were reintroduced to the aggressive mice, they showed an intense fear reaction and avoided the aggressive mice.

Thank you for this important segment. i have read books that mention oxytocin along with other brain chemicals, if levels are low in the brain it will cause problems, of course, makes sense. low brain neurotransmitters can be restored by using amino acids (supplements) eg: tryptophan will increase serotonin and cure depression without the use toxic pharmaceutical drugs that don.t work.
A study using an oral cavity spray of 5-HTP (via the plant source of Griffonia Simplicifolia) has noted that 7.68mg of 5-HTP via 30.72mg of Griffonia Simplicifolia extract taken five times daily (total daily dose of around 40mg) has confirmed an increase in urinary 5-HIAA (from 3.71+/-1.27mg/24 hours to 8.80+/-4.02mg/24 hours; a 137% increase) relative to baseline, confirming that 5-HTP can be absorbed sublingually.[3] Similar results have been noted elsewhere with this spray, although it should be noted that it is confounded with other herbs (detailed in the appetite subsection).[2]
"There was no substance labelled unfit for human use so anyone that tries to bandy that comment around apart from the fact the comment is totally false, we are now starting to accrue our legal case against people that have suggested as such. Under no circumstances was anything ever injected or given to a player which was unfit for human consumption," Dank told ABC News Radio on Sunday.
Established immortalized human PDLCs [22] that maintain the characteristics of primary PDLCs by transfecting human telomerase reverse transcriptase (hTERT) were used. These cell line were kindly provided by Professor Takashi Takata (Hiroshima University, Japan). Cells were cultured in α-MEM supplemented with 10% FBS, 100 U/mL penicillin, and 100 μg/mL streptomycin in a humidified atmosphere of 5% CO2 at 37°C. For the experiments, the cells were seeded into culture dishes and then cultured in α-MEM containing 10% FBS for 2 days until 70% confluent, and, then, the media was replaced by serum-free medium in order to minimize any serum-induced effects on PDLCs. Subsequently, the cells were exposed to H2O2 and human Tβ4 peptide (RegeneRx Biopharmaceuticals Inc., Rockville, MD). All treatments were performed in triplicate and approved by the local ethics committee.

Stimulation of milk ejection (milk letdown): Milk is initially secreted into small sacs within the mammary gland called alveoli, from which it must be ejected for consumption or harvesting. Mammary alveoli are surrounded by smooth muscle (myoepithelial) cells which are a prominant target cell for oxytocin. Oxytocin stimulates contraction of myoepithelial cells, causing milk to be ejected into the ducts and cisterns.
Before the treatment, the female mice were largely indifferent to the cries of a distressed baby, and were even known to trample over them. But after an injection of oxytocin, the mice started to respond more like mothers, picking up the mewling pup in their mouths. Froemke, a neuroscientist at New York University's Langone Medical Center in New York City, was monitoring the animals' brains to find out why that happened.
The biologically active form of oxytocin, commonly measured by RIA and/or HPLC techniques, is also known as the octapeptide "oxytocin disulfide" (oxidized form), but oxytocin also exists as a reduced straight-chain (non-cyclic) dithiol nonapeptide called oxytoceine.[120] It has been theorized that oxytoceine may act as a free radical scavenger, as donating an electron to a free radical allows oxytoceine to be re-oxidized to oxytocin via the dehydroascorbate / ascorbate redox couple.[121]
Work with cell cultures and experiments with animals have shown that administration of thymosin β4 can promote migration of cells, formation of blood vessels, maturation of stem cells, survival of various cell types and lowering of the production of pro-inflammatory cytokines. These multiple properties have provided the impetus for a worldwide series of on-going clinical trials of potential effectiveness of thymosin β4 in promoting repair of wounds in skin, cornea and heart.[17]
Bonding. In the Prairie Vole, oxytocin released into the brain of the female during sexual activity is important for forming a monogamous pair bond with her sexual partner. Vasopressin appears to have a similar effect in males. In people, plasma concentrations of oxytocin have been reported to be higher amongst people who claim to be falling in love. Oxytocin has a role in social behaviors in many species, and so it seems likely that it has similar roles in humans.6
Tβ4 is the major monomeric actin-sequestering peptide in human tissues, and can bind globular actin (G-actin) in a 1:1 ratio and consequently involved in cytoskeletal regulation by inhibiting the polymerization of G-actin into fibrous actin (F-actin) [7]. In addition, Tβ4 is an ubiquitous naturally occurring molecule and is found at concentrations of 1 × 10−5 to 5.6 × 10−1 M in a variety of tissues and cell types, yet, no receptors for the protein have been identified [33]. A recent study suggests that internalization of exogenous Tβ4 is essential for its subsequent cellular functions [34]. Moreover, Tβ4 has been shown to be associated with, wound healing, hair growth, immunomodulation, and angiogenesis [7–9].

Despite this, Tβ4’s place on the banned-substances list is warranted. It reflects the possibility that the effects of the supplement may manifest as a tangible improvement in athletes. However, any time a journalist flippantly declares it “heals damaged tissue and speeds recovery”, it should be noted that such claims are a harmful distortion of the facts.


First, dietary supplements are not regulated as drugs in the US, and the careful testing and quality control that are required of prescription drugs do not apply to supplements like 5-HTP. This is why serious adverse effects and major outbreaks, like the one associated with tryptophan, can occur. You can minimize this risk by using only USP-Verified supplements.

Some work has pointed to a potential dark side to oxytocin. Carter's group found that a single low dose of the hormone given to baby prairie voles improved their pair bonding as adults, but that higher doses interfered with that behaviour — possibly because oxytocin started to activate other receptors16. And human studies have suggested that in certain contexts, a puff of oxytocin can cause people to be more aggressive in defending themselves against outsiders or competitors17. In patients with a psychiatric condition known as borderline personality disorder, a single dose of oxytocin has been found to hinder trust and cooperation18.

The logic behind this trend is that creating tanned skin (by increasing melanin) with minimal to no sun exposure could protect individuals from skin damage, and even potentially lower melanoma risk. More melanin means more protection from UV radiation, and therefore a healthier (and conveniently, deeper) complexion. In this sense, there is perhaps a kernel of truth to the idea of the “healthy glow”.
Oxytocin is typically remembered for the effect it has on prosocial behaviors, such as its role in facilitating trust and attachment between individuals. Consequently, oxytocin is often referred to as the “love hormone".[73][qualify evidence] However, oxytocin has a more complex role than solely enhancing prosocial behaviors. There is consensus that oxytocin modulates fear and anxiety; that is, it does not directly elicit fear or anxiety.[74] Two dominant theories explain the role of oxytocin in fear and anxiety. One theory states that oxytocin increases approach/avoidance to certain social stimuli and the second theory states that oxytocin increases the salience of certain social stimuli, causing the animal or human to pay closer attention to socially relevant stimuli.[75]

Interestingly, there are numerous differences in the biology of teleosts and mammals, as well as specific differences in cardiomyocyte cellular structure and anatomy, all of which might contribute to regenerative variability. Unlike mammals, zebrafish can grow throughout most of adulthood, a phenomenon called “indeterminate growth” (Jordan, 1905). In fact, their growth can be affected markedly by changes in nutrition and population density (Goldsmith et al., 2006). It is thus possible that the capacity to replace cardiac tissue rapidly in teleosts has been retained in evolution as a function of the need for robust animal and cardiac growth. Indeed, a recent study has found that experimentally-induced adult cardiac growth in zebrafish is hyperplastic, and appears to rely on the same signals present or required during cardiac regeneration (Wills et al., 2008).


Increasing trust and reducing fear. In a risky investment game, experimental subjects given nasally administered oxytocin displayed "the highest level of trust" twice as often as the control group. Subjects who were told that they were interacting with a computer showed no such reaction, leading to the conclusion that oxytocin was not merely affecting risk-aversion.[18] Nasally administered oxytocin has also been reported to reduce fear, possibly by inhibiting the amygdala (which is thought to be responsible for fear responses).[19] There is no conclusive evidence for access of oxytocin to the brain through intranasal administration, however.

Letdown reflex in lactating (breastfeeding) mothers, oxytocin acts at the mammary glands, causing milk to be 'let down' into a collecting chamber, from where it can be extracted by sucking at the nipple. Sucking by the infant at the nipple is relayed by spinal nerves to the hypothalamus. The stimulation causes neurons that make oxytocin to fire action potentials in intermittent bursts; these bursts result in the secretion of pulses of oxytocin from the neurosecretory nerve terminals of the pituitary gland.
These proteins became of interest in neurobiology with the finding that in the nudibranch (sea slug) Hermissenda crassicornis, the protein Csp24 (conditioned stimulus pathway phosphoprotein-24), with 4 repeats, is involved in simple forms of learning: both one-trial enhancement of the excitability of sensory neurons in the conditioned stimulus pathway,[25] and in multi-trial Pavlovian conditioning.[26] The phosphorylation of Csp24, in common with post-translational modifications of a number of cytoskeleton-related proteins may contribute to actin-filament dynamics underlying structural remodeling of responsive cells.[26]
Astrocytes constitute the largest population of cells in the central nervous system, constituting approximately 90% of human parenchymal cells. Astrocytes are highly responsive to injury, undergoing rapid hyperplasia and hypertrophy. Astrocytes act as physical and biochemical barriers to axonal regeneration by forming glial scars along ischemic lesions and producing axonal growth-inhibitory proteoglycans. Administration of MSCs significantly attenuates the glial scar in the ischemic boundary and reduces expression of inhibitory proteins, such as Nogo. Analysis of single-cell astrocytes isolated from the ischemic boundary by laser capture microdissection reveals that administration of MSCs dramatically down regulates neurocan, an axonal growth-inhibitory proteoglycan. Coculture of MSCs with astrocytes also substantially reduces neurocan expression in astrocytes activated by oxygen glucose deprivation. These findings suggest that injected MSCs reduce physical and biochemical barriers of astrocytes, which also contribute to axonal and neurite outgrowth.

All of this becomes heavily ironic when you consider that the chemical in question – a hormone called oxytocin – is often billed as the “hormone of love”, and even marketed as “Liquid Trust”. As a new study shows, the reality is much more complicated. Describing oxytocin as the “hormone of love” is like describing a computer as a “writing tool” – it does other things too, some of which aren’t pleasant.
In addition to angiogenesis and neurogenesis, cell- and pharmacologically based therapies substantially remodel white matter in the ischemic brain. Treatment of experimental stroke with MCSs, rhEPO, or sildenafil significantly increases axonal density encapsulating the ischemic lesion. Dynamic changes of white matter structure along the ischemic boundary have been imaged in living animals by diffusion tensor imaging (DTI) and fractional anisotropy (FA) measurements. Data from these MRI indices demonstrate that administration of rhEPO or sildenafil augments axonal remodeling and angiogenesis and that both of them are spatially and temporally correlated. Administration of MSCs, rhEPO, and thymosin beta 4 (Tβ4) dramatically increases the number of oligodendrocyte progenitor cells in the corpus callosum, the striatum, and the V/SVZ of the ischemic hemisphere and mature oligodendrocytes in the ischemic boundary adjacent to myelinated axons. These findings suggest that cell- and pharmacologically based therapies promote generation of oligodendrocyte progenitor cells in the ischemic brain that migrate to target axons, where they extend their processes myelinating the axons.
Bone loss associated with inflammatory diseases, such as rheumatoid arthritis, periodontal disease, and osteoporosis, and elevated osteoclast activity leads to bone destruction [1]. The most common osteolytic disease, periodontitis, is a multi-factorial irreversible and cumulative condition, initiated and propagated by bacteria and host factors [2]. Destruction of peridontal tissue is mediated via the expression of various tissue-destructive enzymes or inflammatory mediators such as interleukins-1 (IL-1), IL-6 and IL-8, tumor necrosis factor- α (TNF- α), nitric oxide (NO), and prostaglandin E2 (PGE2) [2]. Receptor activator of nuclear factor-kappa B (NF-κB) ligand (RANKL) and osteoprotegerin (OPG) are critical for homeostatic control of osteoclast activity, suggesting that they have vital roles in the progression of bone loss in periodontitis [3, 4]. Therefore, resolution of inflammation and blocking osteoclast differentiation might be a potential therapeutic approach for the prevention and treatment of osteolytic inflammatory disease, such as periodontitis [5].
Wow I wonder if it will help those of us with Ehlers Danlos Syndrome – a collagen disorder that causes ligament laxity and makes those with it prone to easy subluxations and early onset arthritis. I have so many injuries from my daily life due to this disorder. I know this won’t fix my faulty collagen since that is encoded in my genes but perhaps it would help with the symptoms – a bunch of torn ligaments and worn out joints. Thanks for sharing!
Although Tβ4 contains only 43 amino acids, it appears to have a wide range of regenerative activities and specific sites on the molecule have been shown to mediate these effects (Goldstein & Kleinman, 2015; Sosne, Qiu, Goldstein, & Wheater, 2010). Both chemically synthesized and recombinant forms have shown efficacy for dermal healing in preclinical models and in human patients (Ehrlich & Hazard, 2012; Kim & Kwon, 2014, 2015; Malinda et al., 1999; Philp, Badamchian, et al., 2003; Philp & Kleinman, 2010; Philp et al., 2006; Ti et al., 2015; Treadwell et al., 2012). A dimeric form has been found to accelerate the rate of dermal healing in an animal model more rapidly than that of the parent molecule (Xu et al., 2013). Tβ4 has also shown repair and regenerative activity in a number of other injury models, such as traumatic brain injury, spinal cord injury, stroke, a model of multiple sclerosis, ischemic limbs, and cardiac damage due to ischemia (Bock-Marquette, Saxena, White, Dimaio, & Srivastava, 2004; Cheng, Kuang, Zhang, Ju, & Wang, 2014; Dube, Bollini, Smart, & Riley, 2012; Morris, Chopp, Zhang, Lu, & Zhang, 2010; Morris et al., 2014; Philp & Kleinman, 2010; Postrach et al., 2014; Smart et al., 2007; Sopko et al., 2011; Ti et al., 2015, Wang et al., 2012; Wei, Kim, Li, Wu, & Gupta, 2014; Xiong, Mahmood, Meng, et al., 2011; Zhang, Zhang, Morris, et al., 2009; Zuo et al., 2013). The processes and pathways for Tβ4-mediated repair are similar in these various tissues and support the observed promotion of dermal healing.
Studies demonstrate that TB-500 is a potent, naturally occurring wound repair factor with anti-inflammatory properties. Tß4 is different from other repair factors, such as growth factors, in that it promotes endothelial and keratinocyte migration. It also does not bind to the extracellular matrix and has a very low molecular weight meaning it can travel relatively long distances through tissues. One of TB-500 key mechanisms of action is its ability to regulate the cell-building protein, Actin, a vital component of cell structure and movement. Of the thousands of proteins present in cells, actin represents up to 10% of the total proteins which therefore plays a major role in the genetic makeup of the cell.
I am not a doctor and this is not to be taken, interpreted or construed as medical advice. Please talk with a licensed medical professional about this. I would say yes though. Just because you dont “know” or “feel” any injury, you might be one functional movement away from a weakened tendon or muscle – snap, crackle and POP! These are just my own personal thoughts and not a prescription or a diagnosis or any form of health care whatsoever.
The scientists discovered that oxytocin strengthens negative social memory and future anxiety by triggering an important signaling molecule -- ERK (extracellular signal regulated kinases) -- that becomes activated for six hours after a negative social experience. ERK causes enhanced fear, Radulovic believes, by stimulating the brain's fear pathways, many of which pass through the lateral septum. The region is involved in emotional and stress responses.
This anti-social effect of a social hormone brings some nuance to the story of oxytocin. In one study, researchers found that Dutch students given a snort of the hormone became more positive about fictional Dutch characters, but were more negative about characters with Arab or German names. The finding suggests that oxytocin's social bonding effects are targeted at whomever a person perceives as part of their in-group, the researchers reported in January 2011 in the journal PNAS.
It turns out oxytocin is responsible for a lot more than just love. New science has found that this amazing molecule also influences how sociable each of us is, allowing us to 'tune in' to the social information around us, perceiving it in much higher resolution. Scientists are now applying this new knowledge in the lab, and as reporter Dr Graham Phillips finds out, they're discovering oxytocin's great potential to treat social disorders, like drug addiction and alcoholism.
5-HTP is very reliable in increasing serotonin levels. 5-HTP is actually used as a clinical test to judge the potency of drugs that affect serotonin levels (by pairing an experimental drug with 5-HTP to induce 'serotonin syndrome', or serotonin toxicity, one can see how much that drug exacerbates serotonin biosynthesis or bioavailability by seeing how much of a 5-HTP dose is required to induce the syndrome; the lower dose indicative of higher drug potency). This test is known as the 5-HTP induced syndrome test.[8]

RegeneRX Biopharmaceuticals is focusing on the commercialization of Tb4 “For the treatment of injured tissue and non-healing wounds, to enable more rapid repair and/or tissue regeneration.” Especially needy are diabetics who suffer from poor blood circulation and loss of sensation of pain that keeps their wounds unnoticed and unattended for days, leading to ulcers that may not heal. Other hard healing wounds are pressure ulcers in patients who are bed ridden and often receive skin grafts as treatment, or reconstructive surgery.
The enzyme dopamine decarboxylase (aromatic L-amino acid decarboxylase) mediates the conversion of 5-HTP into serotonin, and this enzyme is expressed in stomach tissue.[53] Inhibition of this enzyme in the stomach during 5-HTP ingestion is thought to promote the concentration of 5-HTP that reaches neural tissue, which is supported by a study using 100-200mg Carbidopa (pharmaceutical inhibitor) alongside 5-HTP to increase radioactivity of 5-HTP (indicative of neural accumulation) in humans.[54]
Tβ4 is not a thymus-specific peptide but also present in most tissue and all cells except red blood cells [35]. High amounts of Tβ4 were detected in human white blood cells, especially in neutrophils and in macrophages [34], expressed in developing mandible (embryonic day 12) [36] and hair follicles (HF) of mice [37]. In addition, the peptide is also detected outside cells, in blood plasma and in wound and blister fluids [34]. Although the mechanism(s) of action of exogenous Tβ4 on anti-inflammatory effects remains unclear, the high levels of Tβ4 present in human wound fluid (13 μg/mL) suggest its importance in wound healing or anti-inflammation [38]. However, the level of Tβ4 is variable (unchanged, decreased, and increased) in GCF or biopsied gingival tissue of periodontal patients [20, 21]. Based on the observations that Tβ4 has anti-inflammatory effects [11–14], the hypothesis is that Tβ4 regulates inflammatory mediators and osteoclastogenesis in osteolytic bone disease, such as periodontitis.
This sounds very promising and I have a question I’m sure you haven’t heard before. It’s regarding healing. I’m about 230 and avid lifter as well as running occasionally. But I’ve had severe injuries to my l3-s1 for years a d yes I’ve tried some stuff before as far as lifting. But when I was 2 I had encephalitis. I survived it back in 74 which most didn’t however the treatment had left me with migraines and seizures as a child and was told my adult teeth would be very weak when they grew in. So I’m 44 and most of my teeth have broken and I’ve been looking for alternatives to implants. You said both the products mentioned in this article would improve healing and I’ve heard stem cells are capable of regrowing teeth. Would this work for me and how or where would I inject it or maybe do a oral form and let it sit in my mouth for a bit? Never really thought about this but I’ve tried so many clinical trials and been turned down each time. Any info would be greatly appreciated thank you in advance.
The idea that oxytocin is central to social cognition made it an attractive candidate for treating psychiatric disorders, especially autism spectrum disorder. People with this condition, who often have problems with social interaction and communication, may not process social stimuli appropriately — and scientists theorized that oxytocin might reverse some of the symptoms. Beginning in 2010, results emerged that seemed to support this theory: researchers found that single puffs of oxytocin could temporarily improve measures of empathy and social cooperation in people with autism spectrum disorder.
MAPKs and NF-κB played pivotal roles in the development of osteoclasts downstream of RANK signaling [54]. In this study, we demonstrated that Tβ4 activation by Tβ4 peptide inhibited RANKL-induced p38, ERK, JNK MAPK, and NF-κB signaling pathways. These results suggested that Tβ4 activation might inhibit osteoclast differentiation via inhibition of the signaling cascades MAPK/NF-κB/NFATc1.

Interestingly, there are numerous differences in the biology of teleosts and mammals, as well as specific differences in cardiomyocyte cellular structure and anatomy, all of which might contribute to regenerative variability. Unlike mammals, zebrafish can grow throughout most of adulthood, a phenomenon called “indeterminate growth” (Jordan, 1905). In fact, their growth can be affected markedly by changes in nutrition and population density (Goldsmith et al., 2006). It is thus possible that the capacity to replace cardiac tissue rapidly in teleosts has been retained in evolution as a function of the need for robust animal and cardiac growth. Indeed, a recent study has found that experimentally-induced adult cardiac growth in zebrafish is hyperplastic, and appears to rely on the same signals present or required during cardiac regeneration (Wills et al., 2008).
The 10mg powder takes up about 5% of the bag it comes it, meaning you get a greater volume of the powder on your hand than in the spoon your using to find the powder at the bottom of the package. Since dosages are really small, I imagine most of the powder will be wasted. Also the 5-htp powder doesn't seem to dissolve or mix with liquids making it difficult to take. Other than the terrible packaging, the powder itself seems to be of good quality. Recommend it be repackaged in a bag 1/10th of the size, or alternatively, buy the capsules.
Growth factors play an important role is enhancing structural repair of chronic wounds (Robson, 1997). KGF-2 (Robson et al., 2001), TGF-β (Robson et al., 1995), PDGF-BB (Mustoe et al., 1994; Kiritsy et al., 1995; Smiell et al., 1999), β-NGF (Muangman et al., 2004) have been shown to enhance re-epithelialization (Greenalgh, 1996 for review). The KGF-1 gene has been shown to improve cutaneous wound healing in a septic rat model when delivered in a plasmid (Lin et al., 2006). The PDGF-B gene carried in a plasmid mixed with a bovine collagen gel was reported to accelerate closure of patient diabetic ulcers (Mulder et al., 2009; Blume et al., 2011). KGF-2, PDGF-BB and FGF-L are commercially available as RepiferminTM, RegranexTM, and Trafermin to treat human chronic wounds. Data for the effects of PDGF-BB on back wounds of diabetic mice and for the effects of KGF-2 on chronic venous ulcers in patients is tabulated in Tables 10.3 and 10.4. Thymosin β4 accelerated keratinocyte migration in the wounds of old diabetic mice (Philp et al., 2003).
My wife has suffered from debilitating leg cramps for years, usually nocturnal. We have spent much money and time trying to find a cure, including every type of magnesium supplement we could find. Nothing has worked. We’ve also tried MSM and DMSO. Sometimes the cramps are in her calves, sometimes her thighs, sometimes her back and even her toes. Sometimes several muscles cramp at once. She has a high tolerance for pain, but these cramps leave her sobbing. I have purchased TB-500 and received it today. Does your research offer any hope that this could help eliminate her muscle spasms?

Secretion of oxytocin from the neurosecretory nerve endings is regulated by the electrical activity of the oxytocin cells in the hypothalamus. These cells generate action potentials that propagate down axons to the nerve endings in the pituitary; the endings contain large numbers of oxytocin-containing vesicles, which are released by exocytosis when the nerve terminals are depolarised.
Thymosin beta 4 accelerated skin wound healing in a rat model of a full thickness wound where the epithelial layer was destroyed. When Tb4 was applied topically to the wound or injected into the animal, epithelial layer restoration in the wound was increased 42% by day four and 61% by day seven, after treatment, compared to untreated. Furthermore, Tb4 stimulated collagen deposition in the wound and angiogenesis. Tb4 accelerated keratinocyte migration, resulting in the wound contracting by more than 11%, compared to untreated wounds, to close the skin gap in the wound. An analysis of skin sections (histological observations) showed that the Tb4 treated wounds healed faster than the untreated. Proof of accelerated cell migration was also seen in vitro, where Tb4 increased keratinocyte migration two to three fold, within four to five hours after treatment, compared to untreated keratinocytes.
Melanotan II tanning injections have received media attention over the past few years and have been dubbed the "barbie drug" by XXXXXX. The XXXXXX website states that all products are manufactured and compounded in pharmacies in Australia and, pending the satisfactory completion of a short medical assessment, will express post products to a nominated shipping address. The XXXXXX website also states that melanotan II is defined as a 'more potent peptide' when compared to melanotan I, offering a greater density in peptide chain with noticeable results in a shorter timeframe. There are also claims of enhancing male libido, sexual performance, curing erectile dysfunction and as an appetite suppressant.
Treatment with thymosin beta 4 (Tβ4) reduces infarct volume and preserves cardiac function in preclinical models of cardiac ischemic injury. These effects stem in part from decreased infarct size, but additional benefits are likely due to specific antifibrotic and proangiogenic activities. Injected or transgenic Tβ4 increase blood vessel growth in large and small animal models, consistent with Tβ4 converting hibernating myocardium to an actively contractile state following ischemia. Tβ4 and its degradation products have antifibrotic effects in in vitro assays and in animal models of fibrosis not related to cardiac injury. This large number of pleiotropic effects results from Tβ4’s many interactions with cellular signaling pathways, particularly indirect regulation of cellular motility and movement via the SRF–MRTF–G-actin transcriptional pathway. Variation in effects and effect sizes in animal models may potentially be due to variable distribution of Tβ4. Preclinical studies of PK/PD relationships and a reliable pharmacodynamic biomarker would facilitate clinical development of Tβ4.
Neurovascular units within the central nervous system consist of endothelial cells, pericytes, neurons and glial cells, as well as growth factors and extracellular matrix proteins that are close to the endothelium.72,73 Neurovascular units provide niches for neural stem/progenitor cells in the adult brain and, within these units, newly-generated immature neurons are closely associated with the remodeling vasculature. The generation of new vasculature facilitates several coupled neurorestorative processes including neurogenesis and synaptogenesis, which improve functional recovery.74-76 The vascular production of stromal-derived factor 1 and angiopoietin 1 is involved in neurogenesis and promotes behavioral recovery after stroke.77 The disruption of this neurovascular coordination has been observed in a variety of brain conditions including infection, stroke and trauma.78 The injured brain promotes angiogenesis and neurogenesis,13,32,69,79-84 that may contribute to spontaneous functional recovery from injuries such as stroke and TBI. Neurorestorative agents that increase angiogenesis and neurogenesis have been shown to improve functional outcome following brain injury.19,33 Vascular endothelial cells within the neurovascular niche affect neurogenesis directly via contact with neural progenitor cells, while soluble factors from the vascular system that are released into the CNS enhance neurogenesis via paracrine signaling.85 Here, we demonstrate that Tβ4 treatment promotes both angiogenesis and neurogenesis in rats after TBI, suggesting that the neurovascular remodeling at least partially contributes to Tβ4-mediated improvement in functional recovery. A better understanding of molecular mechanisms in the neurovascular niches will be important for developing novel angiogenic and neurogenic therapies for brain injuries.

Tβ4 is not a thymus-specific peptide but also present in most tissue and all cells except red blood cells [35]. High amounts of Tβ4 were detected in human white blood cells, especially in neutrophils and in macrophages [34], expressed in developing mandible (embryonic day 12) [36] and hair follicles (HF) of mice [37]. In addition, the peptide is also detected outside cells, in blood plasma and in wound and blister fluids [34]. Although the mechanism(s) of action of exogenous Tβ4 on anti-inflammatory effects remains unclear, the high levels of Tβ4 present in human wound fluid (13 μg/mL) suggest its importance in wound healing or anti-inflammation [38]. However, the level of Tβ4 is variable (unchanged, decreased, and increased) in GCF or biopsied gingival tissue of periodontal patients [20, 21]. Based on the observations that Tβ4 has anti-inflammatory effects [11–14], the hypothesis is that Tβ4 regulates inflammatory mediators and osteoclastogenesis in osteolytic bone disease, such as periodontitis.

In regards to interventions, one study in treatment resistant depressed persons that combination therapy of 5-HTP with Carbidopa noted that 43 out of 99 (43.4%) patients improved with an average 200mg (variable 50-600mg) dosage of 5-HTP.[24] It has been noted[25] that since Cardidopa is a peripheral decarboxylase inhibitor that can prevent metabolism of monoamines including serotonin[26] that these results are unlikely to reflect monotherapy with 5-HTP, despite being within the 30-45% range sometimes seen with the placebo effect.[25][27]
