Can a supplement proven to fight blue moods also help stimulate weight loss? “Yes it can!” say experts who are now prescribing a natural compound called 5-HTP. According to top integrative health expert Tasneem Bhatia, MD, author of What Doctors Eat ($15.99, Amazon), “5-HTP is converted directly to serotonin, and serotonin makes you feel good, feel happy, feel full — and when you feel that way, you’re going to eat less.” In fact, Dr. Bhatia adds that while most appetite suppressants only target physical hunger, this one also “works to reduce ‘emotional hunger’ and stress-related urges to eat.” Dr. Oz said he left impressed after consulting with a panel of 5-HTP experts, including American Board of Obesity Medicine alum Denise E. Bruner, MD. He said the supplements may even be “a secret weapon for hunger!”
In reality, SSRIs and 5-HTP aren't so different. Both affect serotonin. SSRIs work by blocking serotonin from being reabsorbed by nerve cells so more serotonin is available to help brain cells work efficiently. As a doctor would later tell me, 5-HTP, on the other hand, "provides your body with the tools to make more serotonin, as opposed to antidepressants, which are just working with the serotonin that you have already."
We have evaluated the efficacy of early Tβ4 treatment on spatial learning and sensorimotor functional recovery in rats after TBI induced by unilateral CCI.34 In brief, TBI rats received Tβ4 at a dose of either 6 or 30 mg/kg (RegeneRx Biopharmaceuticals Inc, Rockville, MD) or a vehicle control (saline) administered i.p. starting at 6 hours after injury and then at 24 and 48 hours. Spatial learning was performed during the last five days (31-35 days post injury) using the modified Morris water maze (MWM) test, which is extremely sensitive to the hippocampal injury.35-37 Tβ4-treated TBI rats showed significant improvement in spatial learning when compared to the saline-treated TBI rats. Tβ4 treatment also significantly reduced the swim latency to reach the hidden platform by rats post TBI compared to saline treatment. Using the modified Neurological Severity Score (mNSS) test, our data show that significantly improved scores were observed after TBI in the Tβ4-treated group compared to the saline-treated group. Our data also show that Tβ4 reduced the incidence of both right forelimb and hindlimb footfaults in TBI rats.34 Histological data show that early Tβ4 treatment reduced cortical lesion volume by 20% and 30% for 6 mg/kg and 30 mg/kg, respectively, and reduced hippocampal cell loss. These findings suggest that TB4 provides neuroprotection even when the treatment was initiated 6 hours post injury. In addition, 6-hour Tβ4 treatment promotes neurogenesis in the dentate gyrus (DG) of the hippocampus,38 which may contribute to improvement in spatial learning.
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.
Ok Ben. Thanks. Started the TB 500 for my elbows. Got the 5mg of TB 500 and reconstituted it with 3 cc/ml. of water (3 syringes full) Just about filled the file. Now based on injecting just under .1 cc/ml or just under 10 (8) units for a dose of around 250. How long did that vial last you? Seems like there is a lot left and the amount injected is small. Is my dose and math right?
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.
Work with cell cultures and experiments with animals have shown that administration of thymosin β4 can promote migration of cells, formation of blood vessels, maturation of stem cells, survival of various cell types and lowering of the production of pro-inflammatory cytokines. These multiple properties have provided the impetus for a worldwide series of on-going clinical trials of potential effectiveness of thymosin β4 in promoting repair of wounds in skin, cornea and heart.[17]
Brooke, my mother was prescribed Bpc 157 for leaky gut and chronic ibs. She took it about 30 days, before she saw an improvement. After 45 days she claimed the ibs she suffered with 40 years was gone. Bpc 157 fixed what she thought was not fixable. Her doctor told her to inject sub-q as his patients got better results that way. He said if she couldn’t handle needles they make a capsule form designed to get to gut where it is needed but they are more expensive. The stuff she used was prescribed and compounded by Tailor Made compounding labs, you can get it prescribed for ibs issues.
The need to balance hunting pride and social obligations, and the necessity to reconnect with a family that depends on their provisioning were likely experienced by men throughout much of human evolutionary history. Oxytocin is found in all mammals and originated in the mother-infant bond, where it helps with childbirth, nursing and bonding. In some species, this existing hormonal mechanism could then be harnessed for novel contexts – for instance, men investing in pair-bonding and family provisioning, which is rare among mammals.

Therefore, this study was designed to investigate whether Tβ4 was up-regulated in patients with periodontitis, and this study was also designed to investigate whether Tβ4 inhibition or activation suppressed the osteoclastic differentiation in mouse bone marrow-derived macrophages (BMMs) and inflammatory response in periodontal ligament cells (PDLCs) as well as on their signaling pathways.

What to know about hormonal imbalances While it is natural to experience hormonal imbalances at certain times in life, such as puberty, menopause, and pregnancy, some hormonal changes are related to underlying medical conditions. This article looks at the causes and symptoms of hormonal imbalances in men and women, as well as treatment and home remedies. Read now
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.
The structure of oxytocin is very similar to that of vasopressin (cysteine - tyrosine - phenylalanine - glutamine - asparagine - cysteine - proline - arginine - glycine), also a nonapeptide with a sulfur bridge, whose sequence differs from oxytocin by 2 amino acids. A table showing the sequences of members of the vasopressin/oxytocin superfamily and the species expressing them is present in the vasopressin article. Oxytocin and vasopressin were isolated and synthesized by Vincent du Vigneaud in 1953, work for which he received the Nobel Prize in Chemistry in 1955.
For decades, 5-HTP has been recognized as important to appetite regulation. Higher levels of serotonin are linked to diminished appetite. Keeping serotonin levels from dipping can help keep appetite in check, and may help reduce cravings for carbohydrates. As a serotonin booster, 5-HTP may help to suppress appetite. Research indicates that 5-HTP may be effective in helping people who are overweight or obese lose weight.
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].
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.
Cells were pretreated with indicated concentrations of Tβ4 peptide for 2 hours and then incubated with 200 μM H2O2 for 48 hours (A, B). The mRNAs expression was examined by RT-PCR analysis. This data were representative of three independent experiments. The bar graph shows the fold increase in mRNA expression compared with control cells. * Statistically significant differences compared with the control, p<0.05.
These results were in agreement with previous studies that showed Wnt5a expression can be induced in activated macrophages, endothelial cells, and bone marrow mesenchymal stem cells (BMSCs) after inflammatory stimulation [58, 59]. In addition, we found that the effects of Tβ4 peptide on H2O2-mediated induction of pro-inflammatory cytokines (NO, PGE2, TNF-α, IL-1β, IL-6, IL-8, and IL-17), the expression of inflammatory mediators (iNOS and COX-2), osteoclastogenic cytokines (cathepsin-K, calcitonin receptor or Calcr, NFATc1, and RANK), and osteoclastic differentiation, were reversed by exogenous treatment with Wnt5a siRNA but enhanced by rh-Wnt5a, suggesting that the anti-inflammatory and anti-osteoclastogenetic effects of Tβ4 activation were involved the Wnt5a-dependent signaling pathway. Similar to our results, Wnt5a knock-down markedly reduced cytokine/chemokine production induced by TNF in HDPCs [60].
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.
If you were to go on the internet, read the hype, you'd probably think it'll be something like having an ecstasy tablet or having an orgasm or something like that, but the reality is you probably wouldn't be able to distinguish it from placebo. So the effects are extremely subtle. Now, that subtlety isn't necessarily because of oxytocin itself being a subtle hormone, it's just this issue of it penetrating the brain. So when you take it intranasally, we're still trying to work out how much gets into the brain, but probably only a vanishingly small amount.
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.

Serotonin syndrome (Serotonin toxicity) is caused by an excess of serotonin in the brain. It is most often caused by taking more than one Serotonin-enhancing substance at the same time, such as 5-HTP and an antidepressant medication. Symptoms range in severity according to the level of intoxication and may include increased heart rate, tremor, sweating, mental agitation, seizures, shock, organ failure and death (9).
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
It was also shown recently that delivery of Fgfs by release from peptide nanofibers, a gradual local delivery system, can increase neovascularization and reduce in-farct size in the ischemic rodent heart (Engel et al., 2006). Related to this, zebrafish have a natural ability to synthesize Fgfs after myocardial injury, a signal that appears to recruit Fgf receptor-expressing epicardial-derived cells toward regenerating muscle (Lepilina et al., 2006). Thus, what has been and what will be discovered about zebrafish heart regeneration is quite likely to illuminate possible strategies for enhancing regeneration in the mammalian heart (see Chapter 14.4).
Oxytocin is a peptide of nine amino acids (a nonapeptide). The sequence is cysteine - tyrosine - isoleucine - glutamine - asparagine - cysteine - proline - leucine - glycine (CYIQNCPLG). The cysteine residues form a sulfur bridge. Oxytocin has a molecular mass of 1007 daltons. One international unit (IU) of oxytocin is the equivalent of about 2 micrograms of pure peptide.
To investigate the effect of Tβ4 peptide on H2O2-induced signaling cascades, the activation states of three mitogen-activated protein kinases (MAPKs; p38, c-Jun N-terminal kinase [JNK] and extracellular signal-related kinase [ERK]) as well as NF-κB p65 were examined in PDLCs. H2O2 treatment induced the phosphorylation of p38, ERK, and JNK MAPK(s) and the nuclear translocation of NF-κB p65 (Fig 5A). Treatment of cells with Tβ4 peptide blocked H2O2-induced nuclear translocation of NF-κB p65 and phosphorylation of ERK and JNK (Fig 5B).
Naturalistic studies like ours can help unravel the evolutionary history and function of these hormones. Basically, the fact that hormone mechanisms have been tweaked during evolution suggests that the behaviors they promote have provided fitness benefits in the past. In this case, hunting and sharing meat must have increased men’s reproductive success.
We think that the most important region is the nucleus accumbens, which is kind of up here. The nucleus accumbens is where we can measure a release of the neurotransmitter dopamine when humans or animals take drugs or are exposed to other rewarding stimuli, such as sex. Or gambling, for example, or monetary reward activates the nucleus accumbens as well.
The oxytocin peptide is synthesized as an inactive precursor protein from the OXT gene.[18][19][20] This precursor protein also includes the oxytocin carrier protein neurophysin I.[21] The inactive precursor protein is progressively hydrolyzed into smaller fragments (one of which is neurophysin I) via a series of enzymes. The last hydrolysis that releases the active oxytocin nonapeptide is catalyzed by peptidylglycine alpha-amidating monooxygenase (PAM).[22]
Researchers often investigate the effects of hormones on behavior in laboratory experiments with student subjects. Some studies show that when you give people oxytocin they become more generous and trusting. In others that administer testosterone to men, the opposite happens. The strength of such studies is that they can demonstrate cause and effect – the behavior change only occurs in subjects receiving hormones, not in those who get a placebo. But this research has weaknesses as well: it often focuses on single hormones, ignoring their potential interactions, and behavior is measured with highly artificial tasks.
Showa Denko, the source of up to 60% of all the tryptophan sold in the United States, had used an untested manufacturing process that reduced the amount of activated charcoal used to filter fermented raw tryptophan. Some reports suggest that purity may be a potential problem for 5-HTP as well. No cases of EMS resulting from 5-HTP use have been reported, however.
In a study that hasn’t been published yet, Feldman found that oxytocin receptor genes are also linked to empathy in couples. She looked at variants in the gene that have been linked with an increased risk for autism, a disorder that is marked by major social communication deficits. She found that the more of these “risk variants” a person had, the less empathy they showed toward their partner when that partner shared a distressing experience.
But like most peptides on the market, TB-500 has limited long term studies involving human use. Although I haven’t personally used TB-500 (I can’t, since I compete in WADA sanctioned sports like triathlon and obstacle course racing), from what I’ve seen and heard from bodybuilders and athletes using the peptide, the primary side effect is a temporary sense of lethargy. Also, some people report getting a head rush when injecting TB-500, but report this head rush goes away a few minutes after injecting.
The hormone does not act alone. In 2013, neuroscientist Robert Malenka at Stanford University in California and his colleagues showed that oxytocin works together with the neurotransmitter serotonin to reduce the excitability of neurons in the nucleus accumbens9, a brain region involved in reward. This process seems to support the preference of mice to return to environments where they had rewarding social interactions with other animals. “Oxytocin is part of a system,” Carter says, “and it's not the only molecule that matters, but it's one that in some way is regulatory over a large number of other systems.”
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.
