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.
Uterine contraction: important for cervical dilation before birth, oxytocin causes contractions during the second and third stages of labor.[48] Oxytocin release during breastfeeding causes mild but often painful contractions during the first few weeks of lactation. This also serves to assist the uterus in clotting the placental attachment point postpartum. However, in knockout mice lacking the oxytocin receptor, reproductive behavior and parturition are normal.[49]
Noteworthy:  Many online sources sell an ineffective product.  Also, peptides are fragile by nature and are not effective when they are taken orally (pills, shakes, etc) because they will be broken down by the digestive process. Instead, peptides are mixed with bacteriostatic water and then injected under the skin with an insulin needle. Peptide injections in this manner are nearly painless and have clinically proven effectiveness.
A: 5-HTP stands for 5-hydroxytryptophan. 5-HTP is classified as a dietary supplement; it is made from the seeds of an African plant, Griffonia simplicfolia. 5-HTP is a metabolite (a metabolic by-product) of the amino acid tryptophan, and it is converted by the body into serotonin, which acts in the brain to sooth a person's mind and comfort one from stress and worry. People are using 5-HTP for a variety of conditions, including weight loss, depression, anxiety, PMS, fibromyalgia, eating disorders, obsessive-compulsive disorder (OCD), and headaches. 5-hydroxytryptophan has not been evaluated by the FDA for safety, effectiveness, or purity. One should follow the dosage recommendations on the particular packages of 5-HTP they purchase. According to one researcher, the suggested dosage range of 5-HTP is between 50 mg and 1,200 mg per day, with the usual range being 100 to 600mg. It is always a good idea to check with one
Synthetic oxytocin is sold as medication under the trade names Pitocin and Syntocinon and also as generic oxytocin. Oxytocin is destroyed in the gastrointestinal tract, and therefore must be administered by injection or as nasal spray. Oxytocin has a half-life of typically about three minutes in the blood. Oxytocin given intravenously does not enter the brain in significant quantities - it is excluded from the brain by the blood-brain barrier. There is no evidence for significant CNS entry of oxytocin by nasal spray. Oxytocin nasal sprays have been used to stimulate breastfeeding but the efficacy of this approach is doubtful[24].
If the two things you can't live without are a dark, even tan and a fast-acting, long-lasting erection, then add Melanotan II to your holiday shopping list. This synthetic peptide hormone, which was developed by a research team at the University of Arizona during the late 1990s, darkens skin pigment and may stimulate erectile activity. And despite continued concern and controversy within the medical community regarding its use, it remains available for sale over the internet in a powdered form that can then be reconstituted for subcutaneous injections.
Hi Ben, I have been using TB-500 for minor injury repair assistance for more than 2 years. I have found it to be extremely effective for minor strains to calves, hamstring, shoulder etc. Luckily I have not had to try it for any major injuries. When I first used it I was blown away by how effectively it worked – even to the point that I began to doubt the seriousness of the original injury. When injured I dose at 5mg per week for four weeks then take at least four weeks break. The only side affect I have noticed is a little light headed feeling which passes pretty quickly. I am in my late 40’s and I train hard. TB-500 allows me to train through minor injuries which is great. Love your work
It’s a compound that the body needs in order to make serotonin, which is our main “happiness hormone.” Per Dr. Oz, 5-HTP floods the brain with serotonin and helps minimize stress, sadness, anger, and anxiety. “5-HTP targets specific emotions that drive us to overeat,” Dr. Bhatia explains. And as she already mentioned, 5-HTP also reduces physical hunger pangs and emotional cravings. Ideally, the body makes its own 5-HTP from the amino acid tryptophan, found in foods like turkey and bananas. (Why not just eat more turkey or take a tryptophan supplement? If you struggle with mood or weight, it can be a sign that your body has trouble converting tryptophan to 5-HTP.) Besides making it yourself, the only other way to get 5-HTP is from a supplement. One we like is the BRI 5-HTP Supplement ($16 for 120 capules, Amazon).
An interesting concept that has emerged from initial findings is that regeneration and fibrosis are competing events in the vertebrate heart. That is, if there is a capacity for injury-stimulated cardiomyocyte hyperplasia beyond a certain threshold, regenerative mechanisms will overcome scarring. Results consistent with this idea came from experiments with zebrafish possessing a ts mutation in the cell-cycle checkpoint kinase Mps1 (Poss et al., 2002b). As mentioned earlier, mps1 mutants were initially identified based on their defects in caudal fin regeneration. Serendipitously, mps1 mutants also showed defects in cardiac regeneration at a temperature restrictive for the mutation (Poss et al., 2002b). Instead of regenerating muscle in response to ventricular resection injury, mps1 mutants repaired wounds by forming large, collagen-rich scars. Inhibition of Fgf signaling also stunts cardiac regeneration and causes scarring (Lepilina et al., 2006). These results indicate that even vertebrates with high cardiac regenerative capacity have a default scarring mechanism; normally, regeneration somehow restricts this pathway (Fig. 8). The implication is exciting; perhaps by stimulating regeneration in a poorly-regenerative system like the mammalian heart, scarring events characteristic of myocardial infarction would be restricted by new muscle formation. Similarly, deterring cardiac scarring mechanisms would perhaps favor regeneration in mammals.
Melanotan II is a synthetic analogue of the α-melanocyte stimulating hormone (α-MSH). α-MSH is a melanocortin I receptor agonist which has a role in human pigmentation by stimulating production of eumelanin. As melanotan II is a non-specific melanocortin receptor agonist, it has been reported to cause toxicity effects involving the many physiological systems affected by the receptors.
Pull 1ml of water into the syringe and inject it into the vial with powder. You should never shake the vial when mixing. You should not inject the water directly into the powder with force, but rather let it gently slide down the inside of the vial. If it bubbles up, you should put the vial in the refrigerator and leave it there for about 15-30 minutes. The bubbles will be gone by then. You should then gently rotate the vial between your fingers until all of the powder has dissolved (it takes about 3-4 minutes).
It has been reported that deficiencies in the amino acid tryptophan (precursor to 5-HTP) are correlated with depression, as evidence by serum tryptophan in depressed persons.[16][17] Decreased levels of tryptophan in the body can come from various means but are most likely caused by a diet lacking in the amino acid as substrate, or by upregulation of enzymes (most notably indoleamine 2,3-dioxygenase(IDO) and tryptophan 2,3-dioxygenase(TDO)) that degrade tryptophan or direct it to paths that are not serotonin synthesis causing a relative deficiency.[18][19] These enzymes can be upregulated in states of chronic inflammation[18][20] and injection of some pro-inflammatory cytokines has been implicated in depression[21] and increasing the kyurenine:tryptophan ratio, which is indicative of IDO activity being increased.[22] The activity of tryptophan hydroxylase can also be further downregulated in cases of Magnesium or vitamin B6 deficiency, stress, or excessive tryptophan levels.[7]
Both the production of oxytocin and response to oxytocin are modulated by circulating levels of sex steroids. The burst of oxytocin released at birth seems to be triggered in part by cervical and vaginal stimulation by the fetus, but also because of abruptly declining concentrations of progesterone. Another well-studied effect of steroid hormones is the marked increase in synthesis of uterine (myometrial) oxytocin receptors late in gestation, resulting from increasing concentrations of circulating estrogen.

Injection is the most effective way to administrate the peptide and results are seen the fastest and best. The nasal spray method is effective up to 30 – 40% because the nasal passages have poor absorption rate, you have to apply the nasal spray at least two to three times more than the injection. The injectable product of the Melanotan is very superior as compared to the nasal version. The nasal versions generally take four to five weeks for displaying the results appose to 10 days with the injection.

Oxytocin production is controlled by a positive feedback mechanism. This mechanism allows the release of the oxytocin hormone when a trigger occurs. The hormone then causes an action in the body, such as the letdown of milk or the start of labor contractions, which signals more production of oxytocin. The feedback cycle continues until the action, such as childbirth or feeding the baby, is complete.

Feeding: a 2012 paper suggested that oxytocin neurons in the para-ventricular hypothalamus in the brain may play a key role in suppressing appetite under normal conditions and that other hypothalamic neurons may trigger eating via inhibition of these oxytocin neurons. This population of oxytocin neurons are absent in Prader-Willi syndrome, a genetic disorder that leads to uncontrollable feeding and obesity, and may play a key role in its pathophysiology.[54]
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].
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].

Disclaimer: Thymosin Beta 4 is a peptide that should only be purchased for use in experimentation and research. It should not be purchased for human use or any other purpose than for research. It is advised that once purchased, the peptide is used within experimental circumstances that are under strict lab regulations. It is recommended that researchers use protective gear in order to prevent contact with the substance. However, if exposure is made with the peptide, it is very important to cleanse the area immediately to prevent harm.
MT 1 and MT 2 are synthetic analogues of the alpha-melanocyte stimulating peptide hormone Alpha-MSH. This hormone aids skin cells to produce greater quantities of Melanin. Therefore MT-1 and MT-2 mimic this hormone and encourage the production of more Melanin. Melanin is a dark pigment in the skin that can provide some protection from the UV rays of the sun.
In 1999 researchers in Glasgow University found that an oxidised derivative of thymosin β4 (the sulfoxide, in which an oxygen atom is added to the methionine near the N-terminus) exerted several potentially anti-inflammatory effects on neutrophil leucocytes. It promoted their dispersion from a focus, inhibited their response to a small peptide (F-Met-Leu-Phe) which attracts them to sites of bacterial infection and lowered their adhesion to endothelial cells. (Adhesion to endothelial cells of blood vessel walls is pre-requisite for these cells to leave the bloodstream and invade infected tissue). A possible anti-inflammatory role for the β4 sulfoxide was supported by the group's finding that it counteracted artificially-induced inflammation in mice.
Monomeric β-thymosins, i.e. those of molecular weight similar to the peptides originally isolated from thymus by Goldstein, are found almost exclusively in cells of multicellular animals.[4] Known exceptions are monomeric thymosins found in a few single-celled organisms, significantly those currently regarded as the closest relatives of multicellular animals:[5] choanoflagellates [6] and filastereans.[7] Although found in very early-diverged animals such as sponges, monomeric thymosins are absent from arthropods and nematodes, which do nevertheless possess "β-thymosin repeat proteins" which are constructed from several end-to-end repeats of β-thymosin sequences.[8] Genomics has shown that tetrapods (land vertebrates) each express three monomeric β-thymosins, which are the animal species' equivalents (orthologues) of human β4, β10 and β15 thymosins, respectively. The human thymosins are encoded by the genes TMSB4X, TMSB10 and TMSB15A and TMSB15B. (In humans, the proteins encoded by the two TMSB15 genes are identical.) Bony fish in general express orthologues of these same three, plus an additional copy of the β4 orthologue.[9]

Double immunofluorescent staining for BrdU (red, A) and NeuN (green, B) to identify newborn neurons (yellow after merge, C) in the dentate gyrus of hippocampus from rats examined 35 days after TBI. Micrographs (D) show location of DiI injection in the CA3 region (indicated by white asterisk). In the CA3 region, axons projected from granule neurons in the dentate gyrus will take up injected DiI to their cell bodies. Co-localization (merge, H) of BrdU-positive nuclei (green, F) within retrogradely DiI labeled (red, E) granule cells were examined at 35 days after TBI. Scale bar = 25 μm (C, H). Scale bar = 50 μm (D).
A later experiment by another group took it a step further. This time the volunteers were told how they did, and in half of the cases, they learned that the trustee had burned them and kept the money. The volunteers who were burned were asked whether they wanted to try again. What would you do? This would be like getting that spam from the Nigerian Prince a second time and sending him $5,000 again, right?

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.
5-HTP is sold over the counter in the United States, Canada, the Netherlands, and the United Kingdom as a dietary supplement for use as an antidepressant, appetite suppressant, and sleep aid. It is also marketed in many European countries for the indication of major depression under the trade names Cincofarm, Levothym, Levotonine, Oxyfan, Telesol, Tript-OH, and Triptum.[1]
