For depression: Most commonly, 150-800 mg daily is taken for 2-6 weeks. These doses are sometimes divided up and administered as 50 mg to 100 mg three times a day. Sometimes the dose starts out low and steadily increases every 1-2 weeks until a target dose is reached. Less commonly, higher doses are used. In one study, the dose is steadily increased up to 3 grams per day.

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)”.

"Just that it is completely false that these particular substances and the program wasn't discussed through the highest levels of the club. We have been very firm in terms of our belief in what ASADA, the AFL and Essendon know and for them to remotely suggest that no one knew, to be really blunt, is completely wrong and in some ways offending the process we set up at Essendon Football Club. We were very strict in the protocols we set up."

Young says that the oxytocin field would benefit from closer collaboration between basic and clinical researchers. If basic scientists can work out how oxytocin helps the brain to process social stimuli, then that might help in the design of stimuli — in the form of behavioural therapies — that could be given alongside the hormone to change behaviour, just as oxytocin and pup calls together affect virgin mice. “I think in the future these two branches need to have more communication,” Young says.

But we have to be just as good at recognizing who we can trust, so the system needs fine-tuned control. That’s apparently where oxytocin comes in. The amygdala, that critical organ for our biological risk response, has a high concentration of receptors for oxytocin. In the second set of those gambling experiments with the volunteers and the trustees, researchers used fMRI to watch the brains of the volunteers as they made their choices. As the levels of oxytocin in the brain went up compared with the placebo group, activity in the amygdala went down! Oxytocin diminishes the amygdala’s ability to send out the message “Warning! Warning! I don’t trust this guy.”
The sequence LKKTET, which starts at residue 17 of the 43-aminoacid sequence of thymosin beta-4, and is strongly conserved between all β-thymosins, together with a similar sequence in WH2 domains, is frequently referred to as "the actin-binding motif" of these proteins, although modelling based on X-ray crystallography has shown that essentially the entire length of the β-thymosin sequence interacts with actin in the actin-thymosin complex.[13]
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]
TB-500 is a synthetic fraction of the protein thymosin beta-4, which is present in virtually all human and animal cells. The main purpose of this peptide is to promote healing. It also promotes creation of new blood and muscle cells. The healing effects of TB-500 have been observed in tendons, ligaments, muscle, skin, heart, and the eyes. Thymosin beta-4 is naturally produced in higher concentration where tissue has been damaged. This peptide is also a very potent anti-inflamatory agent.
For this study, one of us, Ben Trumble, followed Tsimane men as they went hunting for food. Typically, Tsimane men set out alone or with a partner in the early morning and search in the forest for prey such as wild pigs, deer, monkeys, or the rare tapir. Following long looping trails they might be gone for eight or nine hours, traveling about six miles (ten kilometers). Ben collected saliva samples throughout the hunt in order to measure changes in men’s hormone levels.
Cardiac effects: oxytocin and oxytocin receptors are also found in the heart in some rodents, and the hormone may play a role in the embryonal development of the heart by promoting cardiomyocyte differentiation.[50][51] However, the absence of either oxytocin or its receptor in knockout mice has not been reported to produce cardiac insufficiencies.[49]

Half the group of burned volunteers got a whiff of Eau de Oxytocin, half got a sniff of Eau de Placebo. Those who sniffed the oxytocin were more trusting and ready to invest with an anonymous trustee a second time than were the placebo-exposed subjects. And when they were asked “Do you want to try this again?” the oxytocin-treated volunteers responded more quickly than the volunteers who hadn’t gotten the nose full of Trust Spray.6
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.
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]
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.

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]

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.
Thymosin Beta 4 is a peptide that was first found within the thymus gland. Since its discovery, other types of thymosin have been found in different tissues throughout test subjects. Thymosin Beta 4 is typically found in both types of muscles – skeletal (the muscles that are required to move) and smooth muscles (such as the heart). When damage occurs in a tissue, Thymosin Beta 4 is upregulated. Then when traumas take place, Thymosin Beta 4 is released in order to help the subject heal from the trauma. This peptide also helps to prevent adhesions from forming, which means there will be less scar tissue and potentially more flexibility. It has potent anti-inflammatory characteristics.
Because of its role in creating serotonin, 5-HTP is indirectly involved in producing melatonin, a hormone that is critical for sleep. Melatonin helps the body’s bio clock stay in sync, and regulates daily sleep-wake cycles. A strong bio clock and regular sleep-wake routines are the cornerstone of healthy, restful, rejuvenating sleep. Research suggests that 5-HTP may help shorten the time it takes to fall asleep and increase sleep amounts.
Combined treatments of 5-HTP and SSRI seem to have strong synergistic effects on serotonin levels in rats and humans so that some clinicians recommend the use of slow-released 5-HTP in combination with SSRIs (R, R2, R3). However, additional clinical trials are required to demonstrate the safety and effectiveness of this approach, and combinations of 5-HTP and medications should only be used under medical supervision.
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.

Touting their discovery as “a great step forward in weight loss history,” the panel were quick to offer up their hard earned cash to back the entrepreneurial pair. “We were shocked. The most we were hoping for was some advice…we weren’t even sure that we would manage to get any investors,” explained Samantha. After outstanding offers from each panel member, the sisters burst into tears.

The RANKL and OPG have been identified as a key regulatory component of alveolar bone loss associated with inflammatory periodontal disease [52]. Moreover, PDLCs were shown to express several osteoclastogenic cytokines, including both OPG and RANKL [30, 31]. Our data demonstrated that Tβ4 peptide abolished H2O2-induced RANKL expression and restored OPG expression. Osteoclasts, bone-resorptive multinucleated cells derived from hematopoietic stem cells, are associated with osteolytic diseases. Furthermore, NFATc1, a master modulator of osteoclastogenesis, regulates target genes, such as cathepsin K and calcitonin receptor or Calcr [53]. In our in vitro study using BMMs, Tβ4 peptide directly and indirectly inhibited RANKL-induced osteoclast differentiation and expression of osteoclast markers, such as cathepsin-K, calcitonin receptor or Calcr, NFATc1, and RANK in BMM cells. These results indicated that Tβ4 was a key therapeutic target in controlling inflammation-induced bone loss.

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].

First developed in the 1980s by researchers at the University of Arizona, Melanotan is principally used for the treatment of skin disorders including vitiligo and erythropoietic protoporphyria that affect skin appearance and sensitivity (especially to sunlight). By promoting melanin in the skin, Melanotan can help ease the symptoms of these conditions and enable those diagnosed to live a more normal life.

20 patients (nine from the 5-HTP group and 11 from the Placebo group) completed the study. Brain tryptophan availability in diabetic patients was significantly reduced when compared to a group of healthy controls. Patients receiving 5-HTP significantly decreased their daily energy intake, by reducing carbohydrate and fat intake, and reduced their body weight.”
The product can be of unknown quality and subject to contamination and stability concerns with use of multi-dose vials. There is no experience with the product other than through unregulated channels. There are health risks from the substance itself and its route of administration – documented in medical literature, case reports as well as reports from NSW PIC.

To identify newborn neurons, double immunofluorescent staining for BrdU/NeuN (mature neuronal marker) was performed (Fig.1). TBI alone significantly increased the number of newborn neurons (NeuN/BrdU-colabeled cells) in the DG of injured hemisphere. Tβ4 treatment significantly further increased the number of newborn neurons compared to saline controls. These data suggest that Tβ4 administration initiated 24 hours after TBI promotes neurogenesis in rats.

I have bee suffering from severe symptoms of post concussion syndrome for several.months after a car accident. The use of TB500 has been the only trratment ease my symptoms and give me my life back. I ceased use last week after 3 weeks and had reoccuring concussion symptoms. As such? I recommenced injections as of last night. Have you read much about the impact of TB500 on brain injury as I’d love to know if more prolonged use would have a permanent impact/remedy for me? Thanks for your time and interest.
The relationship between oxytocin and human sexual response is unclear. At least two non-controlled studies have found increases in plasma oxytocin at orgasm – in both men and women.1718 The authors of one of these studies speculated that oxytocin’s effects on muscle contractibility may facilitate sperm and egg transport.19 Murphy et al. (1987), studying men, found that oxytocin levels were raised throughout sexual arousal and there was no acute increase at orgasm.20 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 that these changes “may simply reflect contractile properties on reproductive tissue.”21
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.

The potential of Tb4 to repair sun damaged and aging skin is yet to be established by extensive studies. Many of the biological events that occur in wounding are involved in skin impaired by sun and aging. Ultraviolet radiation damage or other injuries to skin that are associated with aging may be in the future repairable with Tb4, similar to the success with wound repair. It is a hopeful prediction that this small anti-inflammatory molecule, which plays a vital role in regeneration, remodeling and healing of damaged tissues, would help rejuvenate aging skin. The effects of Tb4 in accelerating wound repair are important following surgery; Tb4 would then have practical applications following cosmetic surgery, a procedure growing in popularity in our society, in dealing with aging skin.
“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.”

While all of the effects described above certainly occur in response to oxytocin, doubt has recently been cast on its necessity in parturition and maternal behavior. Mice that are unable to secrete oxytocin due to targeted disruptions of the oxytocin gene will mate, deliver their pups without apparent difficulty and display normal maternal behavior. However, they do show deficits in milk ejection and have subtle derangements in social behavior. It may be best to view oxytocin as a major facilitator of parturition and maternal behavior rather than a necessary component of these processes.
Like I said, it’s amazing stuff. And it shouldn’t come as a surprise that it affects that amazing part of your brain so intimately involved in keeping you safe…the amygdala. Remember, trust has a lot to do with survival among social animals who depend on each other for safety and protection. Show someone an untrustworthy face, and the amygdala is one of two areas that become more active than anywhere else in the brain.7 It is apparently programmed for reading trust just as it is for snakes or spiders.
Angiogenesis is an essential step in the repair process that occurs after injury. In this study, we investigated whether the angiogenic thymic peptide thymosin beta4 (Tbeta4) enhanced wound healing in a rat full thickness wound model. Addition of Tbeta4 topically or intraperitoneally increased reepithelialization by 42% over saline controls at 4 d and by as much as 61% at 7 d post-wounding. Treated wounds also contracted at least 11% more than controls by day 7. Increased collagen deposition and angiogenesis were observed in the treated wounds. We also found that Tbeta4 stimulated keratinocyte migration in the Boyden chamber assay. After 4-5 h, migration was stimulated 2-3-fold over migration with medium alone when as little as 10 pg of Tbeta4 was added to the assay. These results suggest that Tbeta4 is a potent wound healing factor with multiple activities that may be useful in the clinic.

On the most basic level, a peptide is essentially a small protein. Billions of unique peptides exist, all with different effects and functions in the body. Physiological examples include insulin, oxytocin, and casein, the main protein in milk. Thus, to taunt Essendon supporters for the use of “peptides” is rather non-specific. A much more intelligent insult would be to focus on the administration of thymosin beta-4.
Silencing of the Tβ4 or Wnt5a gene was achieved by transfecting cells with small interfering RNA (siRNA). Cells were transfected with Tβ4 or Wnt5a siRNAs (30 nM) for 24 hours using Lipofectamine 2000 (Invitrogen, Carlsbad, CA, USA) according to the manufacturer's instructions. Cells were transfected with Silencer negative control siRNA using the same protocol.
The tb-500 has a systematic effect regardless of where it is injected. Some believe that thymosin beta-4 should be injected as close to the injury as possible however there is no evidence to show this would be superior. It can be injected subcutaneously (stomach fat) or intramuscularly (shoulders, thighs, buttocks). Injections should be given in different sites (rotated) each time. Depending on the spot, you can either feel nothing or you can feel slight pain - you will learn your favorite spots in time.
It bears understanding that this type of peptide is not a treatment or cure for anything, nor should it be considered a preventative measure to skin cancer. While this tanning peptide is known to protect the skin through the natural tanning process, it is not in and of itself a foolproof UV shield, however it is an excellent way for those who don't tan otherwise to get rich golden tans without as much exposure to the sun.

Exogenous Tβ4 can function like a hormone on cells in terms of its ability to modulate their biological behavior. Since one of the primary roles of Tβ4 in cells is the sequestration of actin monomers, and the protein is not secreted, previously indicated that it was unlikely that Tβ4 could have a hormonal function [42]. However, other studies have shown that the intracellular level of Tβ4 or its mRNA can be significantly and rapidly altered by external stimuli and that change in the level of Tβ4 often are correlated with cell differentiation [18, 43]. In the present study, exogenous Tβ4 peptide activate intracellular Tβ4, which results suggested that exogenous Tβ4 spontaneously enter the cytoplasm through rapid internalization, and acts their functions same as endogenous one [8, 18].
It has been noted[25] that isolated supplementation of 5-HTP may deplete or reduce the bioactivity of catecholamines such as dopamine[44][45][46] (which extends to L-Tryptphan[45]) and that this relationship also acts in reverse, with supplemental L-Tyrosine possibly able to deplete 5-HTP[47][48] and Serotonin itself,[48] which extends to supplemental L-DOPA which may reduce all intermediate of serotonin synthesis[49][50][51] although L-DOPA may also deplete L-Tyrosine (as it is merely later in the same metabolic chain).[50] Due to excessive levels of either one depleting the other, some authors have suggested that combination therapy of 5-HTP and L-Tyrosine (the furthest back in the metabolic chain while still passing rate limiting enzymes) is a potentially useful avenue for anti-depressive effects.[52]
The first time Ditzen and her colleagues did this experiment they found that for both men and women oxytocin improved communication and lowered cortisol, a stress hormone. But in a recent study published in Social Cognitive and Affective Neuroscience, Ditzen and her colleagues measured salivary alpha-amylase (sAA)—an enzyme tied specifically to social stress—and found that men and women responded differently. Women who got oxytocin showed a decrease in sAA whereas men showed an increase and reported feeling more intense emotions. Counterintuitively, these men were also better at communication during conflict: they smiled more, had more eye-contact and were more open about their feelings. These behaviors are essential for peaceful conflict resolution.

Treatment of patients with hyperbaric oxygen has been shown to improve the healing of chronic lower extremity wounds of diabetic patients (Londahl et al., 2010). In a pilot study, this treatment has been shown to more than double the number of circulating vascular stem/progenitor cells in these patients by a mechanism that elevates platelet NOS activity and to stimulate recruitment of vascular progenitor cells to wounds made in their abdominal skin (Thom et al., 2011). This treatment might be combined with topical agents for even greater efficacy in healing chronic wounds.

Traumatic brain injury (TBI) remains a leading cause of mortality and morbidity worldwide. No effective pharmacological treatments are available for TBI because all Phase II/III TBI clinical trials have failed. This highlights a compelling need to develop effective treatments for TBI. Endogenous neurorestoration occurs in the brain after TBI, including angiogenesis, neurogenesis, synaptogenesis, oligodendrogenesis and axonal remodeling, which may be associated with spontaneous functional recovery after TBI. However, the endogenous neurorestoration following TBI is limited. Treatments amplifying these neurorestorative processes may promote functional recovery after TBI. Thymosin beta4 (Tβ4) is the major G-actin-sequestering molecule in eukaryotic cells. In addition, Tβ4 has other properties including anti-apoptosis and anti-inflammation, promotion of angiogenesis, wound healing, stem/progenitor cell differentiation, and cell migration and survival, which provide the scientific foundation for the corneal, dermal, and cardiac wound repair multicenter clinical trials. Here, we describe Tβ4 as a neuroprotective and neurorestorative candidate for treatment of TBI.

Differences among groups were analyzed using a one-way analysis of variance combined with the Bonferroni test. The relative intensities of mRNA and protein bands were assayed using Quantity-One software (Bio-Rad Co., Hercules, CA, USA); results were normalized to the mRNA and protein levels of beta-actin. All values were expressed as mean ± standard deviation. Differences were considered significant at p < 0.05.
The expression of Tβ4 mRNA is cell cycle dependent and is highest at the G0/G1 transition and during S-phase (), and changes in the expression of Tβ4 appear to be related to cell differentiation. It has been reported that hepatocyte growth factor, nerve growth factor or fibroblast growth factor (FGF) can increase the level of Tβ4 mRNA () and, in addition, interferon treatment augments the transcription of the Tβ4 gene (). It has also been shown that increased Tβ4 expression in cancer cells promotes metastasis, possibly by increasing cell mobility.
