Cells that line blood vessels (endothelial cells), taken from human umbilical chord veins, were grown in culture and the layer of cells subjected to a scratch wound. Cultures were then treated with Tb4 or kept in growth medium without Tb4. When examined four hours later, Tb4 treatment attracted cells to migrate into the wound and accelerated their movement, showing it is a chemoattractant. Cell migration was four to six times faster in the presence of Tb4 compared to the migration of untreated cells. Tb4 also hastened wound closure and increased the production of enzymes, called metalloproteases, that could pave the way for angiogenesis by breaking down barrier membranes and facilitating the invasion of new cells to the needy area, to form new vessels. Other experiments showed Tb4 acts in vivo. When endothelial cells were implanted under the skin in a gel supplemented with Tb4, the cells formed vessel-like structures containing red blood cells, indicating the ability to stimulate angiogenesis in the animals.

At SelfHacked, it’s our goal to offer our readers all the tools possible to get optimally healthy. When I was struggling with chronic health issues I felt stuck because I didn’t have any tools to help me get better. I had to spend literally thousands of hours trying to read through studies on pubmed to figure out how the body worked and how to fix it.
Hi..i had 3 major muscle tears(complete)..2 in shoulder and 1in bicep..they all needed surgery for reattachment.. ive done a 20 day round with 157 and believed it helped..im at 7 weeks post op and have about 5 month’s of recovery still to go.. thinking another round of 157..wondering if the TB500 might be a better option or stay with 157? As an athlete and top Spartan racer,im looking to speed up process by any %. Any thoughts/opinions or recommendations are greatly appreciated! Thanks for your help and this info :)
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]
There is a possibility Melanotan may some day present a viable solution to achieving a “healthy tan” in line with current western beauty ideals. But it also creates new forms of risk concerning needle safety, unsettling patient-practitioner relationships via unregulated use, and the subversion of public health messages that groups such as Cancer Council Australia have worked for decades to promote.
I’m curious to know where you got your reconstitution calculation from; you recommend putting approx 3 cc’s in a 5 mg TB-500 which ‘almost fills’ the vial. I have been doing a ton of research on TB-500 and finding contradictory recommendations on how to reconstitute. Because the dosing for TB-500 is higher than what I’m used to with GHRH & GHRP – I felt a lower reconstitution mixture would reduce the amount I needed to take (but now I’m wondering if I’ve been over dosing based on your formula). Would really appreciate knowing how you arrived at filling an insulin syringe ‘three times’ equal to 3 cc’s – just want to make sure i’m dosing correctly
It was under development as drug candidate for female sexual dysfunction and erectile dysfunction but clinical development ceased by 2003, and as of 2018, no product containing melanotan II was marketed and all commercial development had ceased.[1] Unlicensed, untested, or fraudulent products sold as "melanotan II" are found on the Internet, and purported to be effective as "tanning drugs", though side effects such as uneven pigmentation, new nevi (moles), and darkening or enlargement of existing moles are common and have led to medical authorities discouraging use.[2][3]
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).
It should be noted that, anecdotally, 5-HTP is said to reduce cravings for carbohydrates in particular. The serotonergic (related to serotonin) system plays a role in macronutrient selection particular in obese persons with a craving for carbohydrates[13] and enhancing serotonergic transmission is known to reduce these cravings.[14] Beyond this, depressed serotonergic tranmission (hypothalamus) is also implicated in increased eating and reduced satiety in general.[15]
Affecting generosity by increasing empathy during perspective taking. In a neuroeconomics experiment, intranasal oxytocin increased generosity in the Ultimatum Game by 80% but has no effect in the Dictator Game that measures altruism. Perspective-taking is not required in the Dictator Game, but the researchers in this experimental explicitly induced perspective-taking in the Ultimatum Game by not identifying to participants which role they would be in.[20]
At first, the mice showed an irregular smattering of neural impulses when they heard the baby's cries. Then, as the oxytocin kicked in, the signal evolved into a more orderly pattern typical of a maternal brain. The study showed in unusual detail how the hormone changed the behaviour of neurons1. “Oxytocin is helping to transform the brain, to make it respond to those pup calls,” Froemke says.

Actual injection can be done Subq or IM that is - subcutaneous or intramuscular. Injection site does not matter, there is no one site better than others so use one which is more comfortabe to reach, after injection product is absorbed into bloodstream and spread through the body evenly. Subq injection takes place by pinching the skin loose from the muscle and raising it so the needle can be inserted in the fat layer of skin.
5-HTP is an easy way to lose weight on just about any diet, so you can choose any plan that appeals to you — or even no plan at all! But if you’re looking for a quick approach proven to work, use guidelines created by the University of Rome researchers. They allotted folks 1,200 calories a day, about half from carbs and the rest a mix of lean protein and fat. That means at most sittings, you’ll want to start with 200 calories of carbs, including both starchy carbs and carbs from produce (such as a bowl of cereal with fruit, or pasta with veggies). Add about 120 calories of protein (such as some Greek yogurt, egg whites or a few ounces of lean meat). Finish with 80 calories of fat, such as 10 almonds or 2 tsp. olive oil. An easy formula for fast weight loss if we've ever heard one!
Tb4 has other effects that are needed in healing and repair of damaged tissue. It is a chemo-attractant for cells, stimulates new blood vessel growth (angiogenesis), downregulates cytokines and reduces inflammation, thus protecting newly formed tissue from damaging inflammatory events. Tb4 has been shown to reduce free radical levels (with similar efficiency as superoxide dismutase), decrease lipid peroxidation, inhibit interleukin 1 and other cytokines, and decrease inflammatory thromboxane (TxB2) and prostaglandin (PGF2 alpha).

It is highly important to understand that MT2 itself does not protect skin from burning, tan protects your skin. Until some base tan is developed users should still take care not to over-expose skin to uv rays. Starting only with the amount of exposure that the user's skin can handle without burning. It should not take long before the user can handle longer exposures to strong sunlight without adverse effects.
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]
Oxytocin and vasopressin are the only known hormones released by the human posterior pituitary gland to act at a distance. However, oxytocin neurons make other peptides, including corticotropin-releasing hormone and dynorphin, for example, that act locally. The magnocellular neurosecretory cells that make oxytocin are adjacent to magnocellular neurosecretory cells that make vasopressin. These are large neuroendocrine neurons which are excitable and can generate action potentials.[124]

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.

Cells were pretreated with indicated concentrations of Tβ4 peptide for 2 hours and then incubated with 200 μM H2O2 for 48 hours (A-C). Protein expressions were assessed by Western blot analysis (A). The production of NO (B) and PGE2 (C) were measured by Griess reaction and ELISA, respectively. Data replicated the quantifications of NO and PGE2 with the standard deviation of at least three experiments (n = 4). The bar graph shows the fold increase in protein expression compared with control cells. * Statistically significant differences compared with the control, p<0.05. # Statistically significant difference compared with the H2O2—treated group.
Melanotan II non-selectively mimics the action of melanocortin peptides. These are natural hormones involved with pigmentation, energy homeostasis, sexual functioning, the immune system, inflammation, and the cardiovascular system. Much like melanotan I (afamelanotide), melanotan II stimulates the production of eumelanin, causing the skin to go darker (tanning).
In a study measuring oxytocin serum levels in women before and after sexual stimulation, the author suggests it serves an important role in sexual arousal. This study found genital tract stimulation resulted in increased oxytocin immediately after orgasm.[105] Another study reported increases of oxytocin during sexual arousal could be in response to nipple/areola, genital, and/or genital tract stimulation as confirmed in other mammals.[106] Murphy et al. (1987), studying men, found oxytocin levels were raised throughout sexual arousal with no acute increase at orgasm.[107] A more recent study of men found an increase in plasma oxytocin immediately after orgasm, but only in a portion of their sample that did not reach statistical significance. The authors noted these changes "may simply reflect contractile properties on reproductive tissue".[108]
Reconstituting tanning peptide is a part of the process required for use of the product and will require full attention to get proper results. 1 or 2ml sterile water is usually used, diluting with more water will improve dosing accuracy. Lovemelanotan peptide calculator is ideal tool for anyone just starting out and not sure how to reconstitute or dose the product properly.
I am not a doctor and nothing I say should be taken as medical advice. If it were me, I would try TB500, and to inject simply get as close to the injury site as possible. If you want to go into detail feel free to book a consult at

The uterine-contracting properties of the principle that would later be named oxytocin were discovered by British pharmacologist Sir Henry Hallett Dale in 1906,[125][46] and its milk ejection property was described by Ott and Scott in 1910[126] and by Schafer and Mackenzie in 1911.[127] In the 1920s, oxytocin and vasopressin were isolated from pituitary tissue and given their current names. The word oxytocin was coined from the term oxytocic, Greek ὀξύς, oxys, and τοκετός , toketos, meaning "quick birth".


The peripheral actions of oxytocin mainly reflect secretion from the pituitary gland. The behavioral effects of oxytocin are thought to reflect release from centrally projecting oxytocin neurons, different from those that project to the pituitary gland, or that are collaterals from them.[31] Oxytocin receptors are expressed by neurons in many parts of the brain and spinal cord, including the amygdala, ventromedial hypothalamus, septum, nucleus accumbens, and brainstem.[citation needed]
Another interesting agent reported to significantly accelerate chronic wound repair is infrared (700–1200 nm wavelength) and near infrared (600–700 nm) light delivered through lasers or light-emitting diodes (LEDs) (Mester et al., 1968; Rochkind et al., 1989; Conlan, 1996; Schindl et al., 2000; Enwemeka, 2004). Spectroscopic measurements indicate that photons at wavelengths of 630–800 nm penetrate through the skin and muscles of the forearm and lower leg (Chance et al., 1988; Beauvoit et al., 1994, 1995). The effect of the light may be to stimulate cytochrome c oxidase in the mitochondria, resulting in increased oxygen consumption and production of ATP (Karu, 1999).
Melanotans include melanotan I (afamelanotide) and melanotan II. Both melanotan I and II are widely abused to obtain a cosmetic tan. The melanotans are potent, non-selective melanocortin receptor agonists affecting MC1, MC3, MC4 and MC5 receptors. These receptors are responsible for many physiological systems including: pigmentation, energy, sexual function, immune system, inflammation and the cardiovascular system.
Evidence accumulated over the past decades has overturned the traditional dogma that the adult mammalian brain cannot generate new neurons. Adult neurogenesis has been identified in all vertebrate species examined thus far including humans.44-49 Newly generated neuronal cells originate from neural stem cells in the adult brain. Neural stem cells are the self-renewing, multipotent cells that generate the neuronal and glial cells of the nervous system.50 The major function of neurogenesis in adult brain seems to replace the neurons that die regularly in certain brain areas. Granule neurons in the DG continuously die and the progenitors in the subgranular zone of the DG may proliferate at the same rate as mature neuronal death to maintain a constant DG cell number.51 Similarly, the newly proliferated cells from the subventricular zone migrate and replenish the dead olfactory bulb neurons.52 Here, we focus on DG neurogenesis which is important for spatial learning and memory. In normal adult rats, newborn neural cells migrate from the subgranular zone of the DG of the hippocampus into the granule cell layer and eventually become mature granule neurons.53 These new granule neurons extend axonal processes to their postsynaptic targets54-57 and receive synaptic input.58 TBI stimulates widespread cellular proliferation in rats and results in focal neurogenesis in the DG of the hippocampus.59,60 Some of the newly generated granule neurons integrate into the hippocampus. The integration of the injury-induced neurogenic population into the existing hippocampal circuitry coincides with the time point when cognitive recovery is observed in injured animals.44
However, the Food and Drug Administration and its equivalents in other countries have issued repeated advisory notices about Melanotan II, urging consumers to stop using and purchasing this unapproved product. David Carter of the United Kingdom's Medicines and Healthcare Products Regulatory Agency was unequivocal in his denunciation, warning would-be buyers against being "fooled into thinking that Melanotan offers a shortcut to a more even tan." Liverpool John Moores University researcher Michael Evans-Brown cautioned that the peptide may be linked to dyspepsia and various cardiovascular problems, such as increases in blood pressure, while others have noted it appears to stimulate the growth of moles on the body.

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]

A warning: unlike BPC-157, TB-500 is absolutely, 100% banned by WADA and most other global sporting organization both in-competition and out-of-competition. You should NOT use this if you are competing in any such sanctioned sport as it definitely falls under the banned category of “Peptide Hormones, Growth Factors, Related Substances and Mimetics (S2)”.


Last month, in the article “How To Use BPC-157: A Complete Dummies Guide To Healing The Body Like Wolverine“, I introduced the little-known concept of using BPC-157 peptide self-injections and oral BPC-157 peptide consumption (currently completely legal and not banned by sporting organizations) for everything from rapidly healing leaky gut to fixing tendon, ligament and muscle injuries.

An estimated 1.4 million people sustain traumatic brain injury (TBI) each year in the United States, and more than 5 million people are coping with disabilities from TBI at an annual cost of more than $56 billion.1 There are no commercially-available pharmacological treatment options available for TBI because all clinical trial strategies have failed.2,3 The disappointing clinical trial results may be due to variability in treatment approaches and heterogeneity of the population of TBI patients.4-9 Another important aspect is that most clinical trial strategies have used drugs that target a single pathophysiological mechanism, although many mechanisms are involved in secondary injury after TBI.4 Neuroprotection approaches have historically been dominated by targeting neuron-based injury mechanisms as the primary or even exclusive focus of the neuroprotective strategy.3 In the vast majority of preclinical studies, the treatment compounds are administered early and, frequently, even before TBI.10,11 Clinically, the administration of a compound early may be problematic because of the difficulty in obtaining informed consent.12

Kim found that when Americans who carry a particular version of the OXTR gene are more likely to turn to their friends for support when they are distressed. But Koreans react to social stress in a different way – for them, it’s less socially acceptable to turn to friends for support during tough times. And distressed Koreans who carry the same version of OXTR are less likely to seek support from their friends.
Thymosin beta-4 is a naturally occurring peptide, and is found ubiquitously in our cells. A range of studies on animal models have indicated several key biological activities for Tβ4, such as “promot[ing] wound repair, tissue protection, and regeneration in the skin, eye, heart and central nervous system”. Only a handful of clinical trials in humans have attempted to explore these roles practically.
Wonderful column. My expertise is the psychology of risk perception, and I have done some reading on oxytocin and trust (not the kind you want to boost in a bar with Liquid Trust – you can the stuff with pheromones – to boost THAT kind of trust). It turns out there is a high concentration of oxytocin receptors on the amygdala, the area of the brain where fear starts. As oxytocin levels go up, the ability of the amygdala to be warry and more mistrustful goes down. I describe this in Ch. 3 of How Risky Is It, Really? Why Our Fears Don’t Always Match the Facts. A few graphs of which are below. I wonder whether the influence of oxytocin on the amygdala might be connected with the finding of the study you write about.
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.

Few forms of trust are more basic than that between a newborn and its mother. Scientists have discovered that this relationship is strengthened by the hormone oxytocin, released when the baby stares up at mom while breast feeding. Staring lovingly at your boyfriend or girlfriend can trigger their release of oxytocin too, as can warm physical contact like touching and hugging. (Levels increase during sex and peak at orgasm, which may help explain the age-old question “But will you love me in the morning, when your oxytocin levels have dropped?”) Oxytocin reduces stress in arguing couples, helps us recognize faces, even helps us look at a face (in fact, just a pair of eyes) and identify the mood that person is in. The stuff is magic.

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.
In addition, in the Phase 1 clinical trial in healthy volunteers using a randomised, double-blind, placebo-controlled single- and multiple-dose Phase 1 clinical trial, the safety and pharmacokinetics of the intravenous administration of TB-4 was evaluated. From this, intravenous administration of TB-4 appears to be safe and well-tolerated by all subjects with no dose limiting toxicity or serious adverse events reported.
The diverse activities related to tissue repair may depend on interactions with receptors quite distinct from actin and possessing extracellular ligand-binding domains. Such multi-tasking by, or "partner promiscuity" of, proteins has been referred to as protein moonlighting.[14] Proteins such as thymosins which lack stable folded structure in aqueous solution, are known as intrinsically unstructured proteins (IUPs). Because IUPs acquire specific folded structures only on binding to their partner proteins, they offer special possibilities for interaction with multiple partners.[15] A candidate extracellular receptor of high affinity for thymosin β4 is the β subunit of cell surface-located ATP synthase, which would allow extracellular thymosin to signal via a purinergic receptor.[16]

Oxytocin (Oxt; /ˌɒksɪˈtoʊsɪn/) is a peptide hormone and neuropeptide. Oxytocin is normally produced by the paraventricular nucleus of the hypothalamus and released by the posterior pituitary.[3] It plays a role in social bonding, sexual reproduction, and during and after childbirth.[4] Oxytocin is released into the bloodstream as a hormone in response to stretching of the cervix and uterus during labor and with stimulation of the nipples from breastfeeding.[5] This helps with birth, bonding with the baby, and milk production.[5][6] Oxytocin was discovered by Henry Dale in 1906.[7] Its molecular structure was determined in 1952.[8] Oxytocin is also used as a medication to facilitate childbirth.[9][10][11]
5-HTP has been shown in scientific studies to promote relaxation and alleviate stress and anxiety. The relaxation and anti-anxiety properties of 5-HTP appear to come from its ability to elevate levels of serotonin. Research has demonstrated that 5-HTP may reduce the risks of panic attacks and symptoms of panic, as well as anxiety and emotional stress. Research also indicates 5-HTP may be effective in helping to alleviate depression.
