“Ultimately you’re body is going to down-regulate the enzymes needed to convert the tyrosine/l-phenylalanine into dopamine and norepinephrine; this also counts for 5 -htp being converted into serotonin. As far as I’m aware when simply supplementing amino acids to improve neurotransmitter prevalence in the brain, tolerance will build very rapidly within a one week to two week period (from personal experience). Not saying it’s not viable to help out with mood when used sparingly, just saying there’s most likely better ways for continued treatment.”
5-HTP is POSSIBLY SAFE when taking by mouth appropriately. 5-HTP has been used safely in doses up to 400 mg daily for up to one year. However, some people who have taken it have developed a condition called eosinophilia-myalgia syndrome (EMS), a serious condition involving extreme muscle tenderness (myalgia) and blood abnormalities (eosinophilia). Some people think EMS might be caused by an accidental ingredient or contaminant in some 5-HTP products. However, there is not enough scientific evidence to know if EMS is caused by 5-HTP, a contaminant, or some other factor. Until more is known, 5-HTP should be used cautiously.

I found this to be an excellent supplement for myself, which overcomes the rate limiting step when the body converts tryptophan to 5-HTP. I am sleeping much better and handling life's normal stresses better. If you haven't already, become familiar with how/why the body converts L-Tryptophan > 5-HTP > Serotonin > Melatonin. Very interesting! Thank you Bulk Nutrients for making this available.
I have Dupretren’s in my hand. The chords are tightening which is common to this disease pulling the fingers towards the palm. I cannot play guitar any longer. I can still hold a flat palm to the floor when I exercise, but it gets more difficult as the disease takes hold (no pun intended). I’ve read a lot from others inflicted with this. Didn’t like what I read. Hand surgery with modest effects, often adverse effects and too infrequent a fix to the problem. I tried deep tissue massage and scraping too.
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.
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.
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]
Indeed, the findings that progenitor cells of some form exist both in the regenerative zebrafish heart, and in the hearts of less-regenerative mammals supports this idea. Zebrafish have ostensibly found some method to optimize the activity of progenitor cells, perhaps either by maintaining more cells, or by harboring a more cultivating environment for regeneration. Also, both mammalian and nonmammalian hearts contain an epicardial cell layer, yet zebrafish have found some way to activate the epicardium after injury, a process linked with essential neovascularization of regenerating muscle (Lepilina et al., 2006. This result points to the adult mammalian epicardium as a potential cellular source to assist myocardial regeneration or survival. Indeed, mammalian myocardial infarcts typically show poor or insufficient neovascularization, a response that many are trying to improve experimentally. Recent findings have indicated that the G-actin sequestering protein, Thymosin-ß4, may influence the mammalian epicardium. Treatment of adult cardiac explants with Thymosin-ß4 induced the migration of fibroblasts, endothelial and smooth muscle cells as assessed by gene expression and cellular morphology (Smart et al., 2007). In addition, in vivo Thymosin-ß4 treatment could partially restore cardiac survival and function following coronary ligation (Bock-Marquette et al., 2004). Notably, Thymosin-ß4 expression is induced in the injured zebrafish heart, suggesting that fish naturally release this epicardial stimulant on injury (Lien et al., 2006).
5-HTP, along with other L-Tryptophan supplements, have been implicated in the flu-like, potentially fatal Eosinophilic Myalgia Syndrome. This syndrome was initially tied to  impurities - Amino Acids called "Peak E" and "Peak X" - which were present in these products because of poor manufacturing processes by a single major supplier. Some people reject this idea and believe that the syndrome is caused by an excess of tryptophan itself (10, 11).
Thymosin Beta 4 is a potent peptide that comes from a family of 16 related molecules that are localized in circulating cells and tissues within the body. These molecules also have a high conservation of sequence. TB 500 conjoins with actin and prevents actin polymerization. It is noted as being the actin-sequestering molecule within eukaryotic cells. It also boosts extracellular matrix-degrading enzyme production.
Milk ejection reflex/Letdown reflex: in lactating (breastfeeding) mothers, oxytocin acts at the mammary glands, causing milk to be 'let down' into subareolar sinuses, from where it can be excreted via the nipple.[47] Suckling 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.
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]
It has been shown that oxytocin differentially affects males and females. Females who are administered oxytocin are overall faster in responding to socially relevant stimuli than males who received oxytocin.[75][86] Additionally, after the administration of oxytocin, females show increased amygdala activity in response to threatening scenes; however, males do not show increased amygdala activation. This phenomenon can be explained by looking at the role of gonadal hormones, specifically estrogen, which modulate the enhanced threat processing seen in females. Estrogen has been shown to stimulate the release of oxytocin from the hypothalamus and promote receptor binding in the amygdala.[86]
Nasally administered oxytocin has been reported to reduce fear, possibly by inhibiting the amygdala (which is thought to be responsible for fear responses).[76] Indeed, studies in rodents have shown oxytocin can efficiently inhibit fear responses by activating an inhibitory circuit within the amygdala.[77][78] Some researchers have argued oxytocin has a general enhancing effect on all social emotions, since intranasal administration of oxytocin also increases envy and Schadenfreude.[79] Individuals who receive an intranasal dose of oxytocin identify facial expressions of disgust more quickly than individuals who do not receive oxytocin.[75][qualify evidence] Facial expressions of disgust are evolutionarily linked to the idea of contagion. Thus, oxytocin increases the salience of cues that imply contamination, which leads to a faster response because these cues are especially relevant for survival. In another study, after administration of oxytocin, individuals displayed an enhanced ability to recognize expressions of fear compared to the individuals who received the placebo.[80] Oxytocin modulates fear responses by enhancing the maintenance of social memories. Rats that are genetically modified to have a surplus of oxytocin receptors display a greater fear response to a previously conditioned stressor. Oxytocin enhances the aversive social memory, leading the rat to display a greater fear response when the aversive stimulus is encountered again.[74]
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!
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.

Stimulation of uterine smooth muscle contraction at birth: At the end of gestation, the uterus must contract vigorously and for a prolonged period of time in order to deliver the fetus. During the later stages of gestation, there is an increase in abundance of oxytocin receptors on uterine smooth muscle cells, which is associated with increased "irritability" of the uterus (and sometimes the mother as well). Oxytocin is released during labor when the fetus stimulates the cervix and vagina, and it enhances contraction of uterine smooth muscle to facilitate parturition or birth.
Toxicity includes renal dysfunction, rhabdomyolysis, sympathomimetic overdrive, change in size and pigmentation of new moles, with one report of melanoma associated with use of melanotan II. Other case reports include posterior reversible encephalopathy syndrome (consisting of seizures, visual disturbance, confusion, headache, vomiting); refractory priapism, stretching and yawning syndrome; shortness of breath, chest pain, abdominal cramping & pain, dizziness and lethargy.
In persons with Panic Disorders (versus persons without as control) ingesting 200mg of 5-HTP, both groups experienced an increase in salivary cortisol within 3 hours but the persons with Panic Attacks continued to have greater increases after the 3 hour mark; this increased cortisol was independent of any percieved side-effects such as headache, fatigue, perspiration, nausea, etc.[43]

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.
Cognitive impairment has repeatedly been described in bipolar disorders… Serotonin (5-hydroxytryptophan; 5-HT) is possibly involved in these cognitive processes, more particularly in executive functions, learning, memory, and attention. The aim of this study was to investigate serotonergic vulnerability and its relation to cognitive functioning in healthy first-degree relatives of [bipolar disorders] patients…
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]
For those deficient in tryptophan, supplemental tryptophan and 5-HTP could be somewhat effective,[17] although a meta-analysis found barely statistically significant results (Odds Ratio of 1.3-13.2) from a statistically subpar collection of studies, and based on the inclusion criteria it set it had to expand its analysis to both 5-HTP and Tryptophan to get two studies to assess.[23]
Hi Ben. Have a groin problem which I have had for years and it just won’t go away it’s not a hernia or osteitis pubis I had an MRI and the specialist said they wouldn’t operate. I can still play sport but I’m just less agile and slower than normal and it takes a few days for the groin pain to go away after sport. Would tb500 help to heal it or would bpc157 or something else be better? Thanks :)
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.

With the TB-500 it seems that pain was reduced even more in my shoulder and it appears that I recovered much faster from my workouts. I took the TB-500 on rest days. I have two more 1mg doses of TB-500 and I am going to site inject intramuscularly to the shoulder to see what happens. Then I will stop taking both for a month to see how things work out. Hopefully I won’t need them again.
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.

Lovemelanotan peptide calculator is ideal tool for anyone just starting out and not sure how to reconstitute or dose the product properly.
Supplementation of 5-HTP has been shown to be more effective than tryptophan supplementation alone. This additional benefit of 5-HTP supplementation arises because 5-HTP bypasses the cell's L-tryptophan's own self-regulation on the IDO enzyme, in which it upregulates the activity of IDO (discussed in next section) to maintain body homeostasis of tryptophan[6] and it bypasses the tryptophan hydroxylase enzyme, which is the rate limiting step in serotonin biosynthesis.[7]

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]
Hi Ben..my question is this, I have a 9 year old german shepard..his back end is all of a sudden weak, where he will fall over,like he can’t hold himself up, I can see extreme weaknes inhis hide quarter.The vet has taken many x-rays and blood work, but all comes back perfect.Do you think this pepetide would help my dog?..he is 101 pounds, extremely strong, Walking is his issue, he can run like the wind, then he can fall over.Any help would be greatly appreciated.

The main functionality of TB500 hinges on the ability to upregulate cell building proteins such as actin, which is a protein that forms (together with myosin) the contractile filaments of muscle cells, and is also involved in motion and metabolism in many other types of cells.. Upregulation of actin allows TB500 to promote healing, cell growth, cell migration and cell proliferation. This not only helps build new blood vessel pathways but also upregulates the type of “good” inflammation that is directly correlated with faster wound healing.
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
If cupid had studied neuroscience, he’d know to aim his arrows at the brain rather than the heart. Recent research suggests that for love to last, it’s best he dip those arrows in oxytocin. Although scientists have long known that this hormone is essential for monogamous rodents to stay true to their mates, and that it makes humans more trusting toward one another, they are now finding that it is also crucial to how we form and maintain romantic relationships.

Loading is not absolutely necessary, it is only done to achieve results faster. Loading means taking doses more frequently to build up initial tan faster thus getting in tan maintenance mode sooner. Typical loading is done by taking 0.5mg once a day until desired skin tone is achieved. Loading dose can slightly vary from person to person, depending on skin type, bodyweight and other factors, but 0.5mg is pretty standard for most

Plain sterile water is the most suitable diluent for TB-500. Alternatively it can be reconstituted with sterile saline (0.9% NaCl) or sterile bacteriostatic water (0.9% sodium chloride). Plain sterile water should be readily available to buy without prescription in any local pharmacy. Alternatively it can also be purchased online. It is even available on ebay.


There is one glaring problem, however: the supplements come with a disclaimer that recommends not taking them for more than three months. Most of the information out there on 5-HTP is anecdotal, and most of them are stories of it helping people, rather than hard facts about its scientific properties. I approached neurologists, psychologists and experimental doctors about 5-HTP, and many responses were strange. Not many people were willing to speak about it, saying they weren't qualified or hadn't read the relevant material, but there isn't much material to speak of. The main source of legitimate scientific evidence came from the University of Maryland Medical Center website, who stated that 5-HTP may work as well as certain antidepressant drugs to treat people with mild-to-moderate depression. But all the studies that support that statement were done in the 1980s and 1990s. I wanted to know if 5-HTP was a realistic alternative to SSRIs. Could I stay on 5-HTP forever, basking in its natural glory?

5-HTP, along with other L-Tryptophan supplements, have been implicated in the flu-like, potentially fatal Eosinophilic Myalgia Syndrome. This syndrome was initially tied to  impurities - Amino Acids called "Peak E" and "Peak X" - which were present in these products because of poor manufacturing processes by a single major supplier. Some people reject this idea and believe that the syndrome is caused by an excess of tryptophan itself (10, 11).

Humans are social animals. Our individual prospects depend to a significant degree on the prospects of the group(s) to which we belong, and how well we get along with the group(s). Survival means being acutely sensitive to who is on our side and who is not. So it isn’t surprising that trust matters so much to how we go about protecting ourselves. And it isn’t surprising to find the instinct for trust rooted deep in the brain.
But what about the three-month warning? Dr Rush, while an advocate for the supplement, sees it as a short-term solution, and not something to rely on long-term, for good reason. "Technically taking 5-HTP alone can deplete important brain chemicals such as dopamine and adrenaline. While 5-HTP is aimed at increasing the amount of serotonin in the body, dopamine and adrenaline are also important for positive mental health states. In order to prevent the depletion of important brain chemicals, taking 5-HTP would need to be balanced with amino acids that support the production of dopamine and adrenaline." That's L-Tyrosine, which you eat in soy, chicken and beef, and can also be found in health food shops as a supplement.

Surgery: 5-HTP can affect a brain chemical called serotonin. Some drugs administered during surgery can also affect serotonin. Taking 5-HTP before surgery might cause too much serotonin in the brain and can result in serious side effects including heart problems, shivering, and anxiety. Tell patients to stop taking 5-HTP at least 2 weeks before surgery.
