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.
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.
Mouse bone marrow macrophage (BMMs) of 5-week-old female ICR mice (Charles River Laboratories, Seoul, South Korea) were used as previously described [23]. Animals were maintained in accordance with the National Institute of Toxicological Research of the Korea Food and Drug Administration guideline for the humane care and use of laboratory animals Institutional Animal Care and Use Committee (IACUC) approval was obtained from Kyung Hee University (Seoul, Korea). Briefly, bone marrow of tibiae and femurs of mice were flushed with α-MEM. After removing erythrocytes with hypotonic buffer, cells were cultured in α-MEM containing 10% FBS for 24 h and adherent cells were discarded. Non-adherent bone marrow cells were transferred onto 100-mm non-coated petri dishes at 5×106 cells per dish and cultured in the presence of M-CSF (30 ng/ml) for 3 days. Condition medium (CM) was obtained from HPDLCs treated with 200 μM H2O2 or Tβ4 (0.5, 1 and 5 μg/mL) for 2 days. To evaluate the osteoclastogenic activity of CM from HPDLCs, we added the CM mixture (60% CM plus 40% fresh α-MEM without M-CSF or RANKL) or rh-Tβ4 to pre-osteoclast-stage cells and further cultured the cells for up to 5 days to achieve mature osteoclast differentiation BMMs (1.5 × 105 cells/well) and PDLCs (1.5 × 104 cells/well) were co-cultured for 7 days in the presence of M-CSF (30 ng/ml), RANKL (100 ng/mL), H2O2 (200 μM) or Tβ4 (0.5, 1 and 5 μg/mL) in α-MEM, supplemented with10% in 48-well plates under 5% CO2 atmosphere.
Other supplements are available which have appetite supressant and mood enhancing effects similar to 5-HTP. These type of ingredients are often included, in optimal pre-formulated dosages in fat burners. Phenylethylamine is also another ingredient with mood enhancing potential that is often found in fat burners in place of 5-HTP. 5-HTP can be found in some sleep supplements, though in Australia they are replaced by ingredients such as GABA and phenibut.

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].
Beta thymosins are a family of proteins which have in common a sequence of about 40 amino acids similar to the small protein thymosin β4. They are found almost exclusively in multicellular animals. Thymosin β4 was originally obtained from the thymus in company with several other small proteins which although named collectively "thymosins" are now known to be structurally and genetically unrelated and present in many different animal tissues.
To determine the direct effect of Tβ4 peptide on osteoclastogenesis, mouse BMMs were directly exposed to Tβ4 peptide. Direct treatment with Tβ4 peptide also reduced the number of multinucleated TRAP-positive cells and TRAP activity in a dose-dependent manner (Fig 7A and 7B). Since Tβ4 downregulated H2O2-induced various cytokines expression, the indirect effect of Tβ4 on osteoclast formation through PDLC cells using co-culture system were investigated. After addition of Tβ4 peptide to the BMMs-PDLCs co-culture, the number of osteoclast and TRAP activity were also significantly decreased (Fig 7C and 7D).
About ten years ago, psychology studies started to show that single doses of oxytocin, delivered through an intranasal spray, could promote various aspects of social behaviour in healthy adults. People who inhaled oxytocin before playing an investment game were more willing to entrust their money to a stranger than were placebo-treated players10. A dose of the hormone also increased the amount of time that people spent gazing at the eye region of faces11, and improved their ability to infer the emotional state of others from subtle expressions12.
Virtually all vertebrates have an oxytocin-like nonapeptide hormone that supports reproductive functions and a vasopressin-like nonapeptide hormone involved in water regulation. The two genes are always located close to each other (less than 15,000 bases apart) on the same chromosome and are transcribed in opposite directions. It is thought that the two genes resulted from a gene duplication event; the ancestral gene is estimated to be about 500 million years old and is found in cyclostomes (modern members of the Agnatha).[12]
I was kind of scared because I ran across some threads that said TB500 leads to cancer or promotion of benign tumors…most of these were at least 4-5 years old though and it seems there are countless logs online all with good experiences. Nonetheless I was still worried so I did some more research and came across a pharmaceutical company in the US doing clinical trials for thymosin beta 4 to help with dry eye syndrome. I have attached some links. This makes me feel much safer but if you have any more insight I’d really appreciate it.

For example, when a mother is nursing her baby, that stimulation from the breast is going into the brain and causing those oxytocin neurons to fire and release oxytocin directly into the brain. That's much more powerful than what happens with a nasal spray. So I think that, you know, in the future, we may have these drugs that can, in a very potent way, tap into this oxytocin system to treat many different kinds of disorders.

Oxytocin has been of keen interest to neuroscientists since the 1970s, when studies started to show that it could drive maternal behaviour and social attachment in various species. Its involvement in a range of social behaviours2, including monogamy in voles, mother–infant bonding in sheep, and even trust between humans, has earned it a reputation as the 'hug hormone'. “People just concluded it was a bonding molecule, a cuddling hormone, and that's the pervasive view in the popular press,” says Larry Young, a neuroscientist at Emory University in Atlanta, Georgia, who has been studying the molecule since the 1990s.
A: While it is possible there is an interaction, it most likely is not severe or life-threatening. Keep in mind that the "T" in HTP stands for tryptophane, which is an essential amino acid that your body processes routinely. The most common interaction involved with 5-HTP is with antidepressants or other medications that are intended to affect brain chemistry, as 5-HTP is converted into serotonin, an important brain chemical that helps regulate mood.
In 20 persons undergoing alcohol withdrawal taking 5-HTP (5mg) alongside Glutamine (150mg) and D-Phenylalanine (300mg) and some minerals such as Calcium and Magnesium, it was noted that after 40 days of nutritional therapy (in a hospital setting) that all withdrawal symptoms assessed via SCL-90-R except for anxiety noted a greater reduction with nutritional support relative to placebo.[1]

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.
Liver fibrosis, a major characteristic of chronic liver disease, is inappropriate tissue remodeling caused by prolonged parenchymal cell injury and inflammation. During liver injury, hepatic stellate cells (HSCs) undergo transdifferentiation from quiescent HSCs into activated HSCs, which promote the deposition of extracellular matrix proteins, leading to liver fibrosis. Thymosin beta 4 (Tβ4), a major actin-sequestering protein, is the most abundant member of the highly conserved β-thymosin family and controls cell morphogenesis and motility by regulating the dynamics of the actin cytoskeleton. Tβ4 is known to be involved in various cellular responses, including antiinflammation, wound healing, angiogenesis, and cancer progression. Emerging evidence suggests that Tβ4 is expressed in the liver; however, its biological roles are poorly understood. Herein, we introduce liver fibrogenesis and recent findings regarding the function of Tβ4 in various tissues and discuss the potential role of Tβ4 in liver fibrosis with a special focus on the effects of exogenous and endogenous Tβ4. Recent studies have revealed that activated HSCs express Tβ4 in vivo and in vitro. Treatment with the exogenous Tβ4 peptide inhibits the proliferation and migration of activated HSCs and reduces liver fibrosis, indicating it has an antifibrotic action. Meanwhile, the endogenously expressed Tβ4 in activated HSCs is shown to promote HSCs activation. Although the role of Tβ4 has not been elucidated, it is apparent that Tβ4 is associated with HSC activation. Therefore, understanding the potential roles and regulatory mechanisms of Tβ4 in liver fibrosis may provide a novel treatment for patients.
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.
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
When looking at studies that investigate carbohydrates per se, one study in overweight women given 8mg/kg 5-HTP for 5 weeks noted that while placebo did not reduce carbohydrate ingested (calories were reduced in placebo, but carbohdyrate remained at 38% of voluntary calorie intake) that 5-HTP also retained 38% of intake as carbohydrates despite consuming less calories and carbohydrates in total.[9] A decrease in both carbohydrate and dietary fat has been noted with 750mg 5-HTP daily for 2 weeks in diabetics (with no dietary guidelines given), but appeared to be reduced to a similar degree as calories overall.[10] Only one study supports these anecdotes, where the reduction in calories seemed to be acounted mostly for by carbohydrates (75% of observed reduction) and then fats (25%).[10]
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]
At least one study has actively differentiated between 'an increase in satiety' (sensation of fullness from food) and a 'decrease in appetite' (less desire to eat) and noted that 5-HTP causes an increase in satiety without a concomitant decrease in appetite.[9] Additionally, most studies are in exclusively females which may have more significance with interventions pertaining to serotonin metabolism; only one study mentioned above was conducted in men as well[10] but appears to suggest that it benefits both genders.
Do not fall for the easier methods of using MT-2, injections is the only proper way of using this peptide. Many Internet suppliers will sell things like nasal sprays, pre-mixed peptide, oral pills and powders, they simply don't work, if they did no one would use injections, right? There are a some positive reports of nasal spray experience, however its not very cost effective as peptide molecules in this form are large and difficult to pass the nasal membrance, there is some effect, but its minor comparable to injection route where absorption rate is 100%. Similarly, pills of this type are also quite useless because enzymes within the stomach will render the peptide inert.
Established immortalized human PDLCs [22] that maintain the characteristics of primary PDLCs by transfecting human telomerase reverse transcriptase (hTERT) were used. These cell line were kindly provided by Professor Takashi Takata (Hiroshima University, Japan). Cells were cultured in α-MEM supplemented with 10% FBS, 100 U/mL penicillin, and 100 μg/mL streptomycin in a humidified atmosphere of 5% CO2 at 37°C. For the experiments, the cells were seeded into culture dishes and then cultured in α-MEM containing 10% FBS for 2 days until 70% confluent, and, then, the media was replaced by serum-free medium in order to minimize any serum-induced effects on PDLCs. Subsequently, the cells were exposed to H2O2 and human Tβ4 peptide (RegeneRx Biopharmaceuticals Inc., Rockville, MD). All treatments were performed in triplicate and approved by the local ethics committee.
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.
I’m always interested in learning about better supplements for my health. I’ve heard a lot of good things about peptides, but this was the first time I’ve read about TB-500 in particular. It sounds like it can have a major impact on helping you recover from injuries, which is a huge deal in today’s world. I may need to look into it some more before actually buying it, but thank you so much for taking the time to explain it!
“Further analysis by gender revealed that females in the 5-HTP group had a significantly lower panic rate and intensity of cognitive symptoms whereas, in males, the effect of 5-HTP was limited to lowering the intensity of somatic panic symptoms. Thus, an increased availability of 5-HT may have a gender-dependent protective effect in CCK-4-induced panic.”
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.

Cells were pretreated with indicated concentrations of Tβ4 peptide for 2 hours, post-incubated with 200 μM H2O2 for 48 hours, and then conditioned medium (CM) was collected. Mouse BMMs were cultured with CM in the presence of M-CSF (30 ng/mL) and RANKL (100 ng/mL), as described in Materials and methods. After 5 days, cells were fixed and stained for TRAP as a marker of osteoclasts (A), and the number of TRAP-positive multinucleated cells (MNCs) was scored (B). TRAP osteoclast activity was assayed using the TRAP cytochemical stain technique (C). * Statistically significant differences compared with the control, p<0.05. The data presented were representative of three independent experiments.


For all its positivity, however, oxytocin has a dark side. Or, more accurately, it plays a more complex role in human behavior than is commonly thought. As a facilitator of bonding among those who share similar characteristics, the hormone fosters distinctions between in-group and out-group members, and sets in motion favoritism toward in-group members and prejudice against those in out-groups. Ongoing research on the hormone is a potent reminder of the complexity of biological and psychological systems.
Such tissue-regenerating properties of thymosin β4 may ultimately contribute to repair of human heart muscle damaged by heart disease and heart attack. In mice, administration of thymosin β4 has been shown to stimulate formation of new heart muscle cells from otherwise inactive precursor cells present in the outer lining of adult hearts,[18] to induce migration of these cells into heart muscle[19] and recruit new blood vessels within the muscle.[20]

According to recent research, this hormone “is now believed to be involved in a wide variety of physiological and pathological functions such as sexual activity, penile erection, ejaculation, pregnancy, uterine contraction, milk ejection, maternal behavior, social bonding, stress and probably many more, which makes oxytocin and its receptor potential candidates as targets for drug therapy. From an innocuous agent as an aid in labor and delivery, oxytocin has come a long way in being touted as the latest party drug.”4

In conclusion, this study is the first study to demonstrate that down-regulation of Tβ4 was observed in an in vitro model of H2O2-stimulated PDLCs. Tβ4 activation had anti-inflammatory effects via MAPK and NF-κB pathways in PDLCs and anti-osteoclastogenic effects via MAPK, NF-κB, and Wnt5a pathways in BMMs. These findings supported the fact that Tβ4 peptide could possibly be used in the development of a therapeutic drug for periodontitis and osteolytic disease.
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.
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]
