Skin is the largest organ of the body, which makes up 16% of total body weight. It is also the largest organ that provides immune protection and plays a role in inflammation. Composed of specialized epithelial and connective tissue cells, skin is our major interface with the environment, a shield from the outside world and a means of interacting with it. As such, the skin is subjected to insults and injuries: burns from the sun’s ultraviolet radiation that elicit inflammatory reactions, damage from environmental pollutants and wear and tear that comes with aging.

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.
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.”
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?
In humans, 5-HTP is the nutrient precursor to the neurotransmitter serotonin – widely known as the 'happy neurotransmitter' – meaning 5-HTP converts directly into serotonin in the brain. As well as being in our bodies, it's found naturally in the seeds of a woody shrub native to West Africa. By taking it as a supplement, in theory, you will end up with more serotonin in your brain. Serotonin deficiency is linked to depression, anxiety and a whole host of physical and mental ailments. Raising its levels seems to help brain cells send and receive chemical messages, which in turn boosts mood.
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.
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.

Bromodeoxyuridine (BrdU), a thymidine analogue, can be incorporated into the DNA of dividing cells and is widely used to label new cells.61-63 To label proliferating cells, BrdU (100 mg/kg) was injected i.p. daily starting at day 1 post TBI for 10 days. The number of BrdU-positive cells found in the ipsilateral cortex, DG, and CA3 areas was significantly increased 35 days after TBI compared with sham controls.18,34,64,65 Tβ4 treatment further increased the number of BrdU-positive cells compared to saline controls.34 The increased number of BrdU-positive cells may result from effects of Tβ4 on either increasing cell proliferation or reducing cell death of newborn cells. Our recent data show Tβ4 increases oligodendrocyte precursor cell proliferation and differentiation in animal models of stroke25 and experimental autoimmune encephalomyelitis.27 Tβ4 may not directly affect cell proliferation but inhibit cell death, for example, in corneal and conjunctival epithelial cells treated with benzalkonium chloride in vitro66 and endothelial precursor cells under serum deprivation.67 Our data further show that neurogenesis increases in TBI rats treated with Tβ4, suggesting that Tβ4 promotes newborn cells to differentiate into neurons. This is consistent with the effect of Tβ4 on promoting epicardium-derived progenitor cell differentiation into endothelial and smooth muscle cells to form the coronary vasculature.22 Whether the increased number of BrdU-positive cells in the brain of TBI rats treated with Tβ4 is tissue specific remains unknown. Tβ4 may not directly affect cell proliferation. Increased cell proliferation and neurogenesis are also possibly secondary to that Tβ4-mediated angiogenesis, as described later.
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 cornea is the outer thin layer of epithelial cells protecting the eye. After wounding, timely resurfacing of the cornea with new cells is critical, to prevent loss of normal function and loss of vision. Corneal epithelial healing occurs in stages, with cells migrating, dividing and differentiating. Therapies for corneal injury are limited. Therefore, the recent finding that Tb4 promotes corneal wound repair in animal models offers hope for a therapeutic product that will improve the clinical outcome of patients with injured corneas.

The activity of the PAM enzyme system is dependent upon vitamin C (ascorbate), which is a necessary vitamin cofactor. By chance, sodium ascorbate by itself was found to stimulate the production of oxytocin from ovarian tissue over a range of concentrations in a dose-dependent manner.[23] Many of the same tissues (e.g. ovaries, testes, eyes, adrenals, placenta, thymus, pancreas) where PAM (and oxytocin by default) is found are also known to store higher concentrations of vitamin C.[24]


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.

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


But this isn’t the only study to show the subtle side of oxytocin. Just three months ago, I wrote about research from Heejung Kim at the University of California, which showed how oxytocin’s effects vary across different cultures. To fulfil its many roles, oxytocin has to dock at a protein called the ‘oxytocin receptor’, encoded by a gene called OXTR.


The vascular system in the normal adult brain is stable, but is activated in response to certain pathological conditions including injuries.68 Von Willebrand factor (vWF) staining has been used to identify vascular structure in the brain after TBI.69 TBI alone significantly increased vascular density in the injured cortex, CA3, and DG of the ipsilateral hemisphere when examined at day 35 after TBI compared to sham controls.18,34,64,65 Tβ4 treatment significantly increased the vascular density in these regions compared to saline treatment.34 This is in agreement with in vitro and in vivo pro-angiogenic effect of Tβ4.70,71

Establishment of maternal behavior: Successful reproduction in mammals demands that mothers become attached to and nourish their offspring immediately after birth. It is also important that non-lactating females do not manifest such nurturing behavior. The same events that affect the uterus and mammary gland at the time of birth also affect the brain. During parturition, there is an increase in concentration of oxytocin in cerebrospinal fluid, and oxytocin acting within the brain plays a major role in establishing maternal behavior.


Oxytocin production does not exist separately from the evolved neurophysiological mechanisms that regulate gonadotropin releasing hormone (GnRH) pulsatility. There are mammalian pheromones that are known to directly influence the GnRH pulse, for example androstenol. Oxytocin is not considered to be a pheromone by anyone I know who is involved in olfactory research. Sniffing it is simply a delivery method that we now can see might have negative consequences.

Animal studies have found high levels of both stress and oxytocin in voles that were separated from other voles. However, when the voles were given doses of oxytocin, their levels of anxiety, cardiac stress, and depression fell, suggesting that stress increases internal production of the hormone, while externally supplied doses can help reduce stress.
When we asked a group of readers to test out 5-HTP to lose weight, they ate unlimited portions of healthy food and still shed up to five pounds in a week. We also talked to women who’d been using 5-HTP long term. Heather Miars started taking 5-HTP for her mood at Dr. Bhatia’s urging. “I was finally able to go off prescription antidepressants and lose 15 pounds!” recalls the 45-year-old mom. Meanwhile, Audra Holmes tried 5-HTP after developing “mood swings so wild, I was giving people whiplash,” she jokes. On 5-HTP, she says: “I didn’t have the highs and lows. I could suddenly get through the day without naps or comfort food!” She shed 50 pounds in 16 weeks. Wish you could have the same kind of success with an easy way to lose weight? As Dr. Oz put it: “5-HTP may be your pre-meal must-have!”
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.
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).
One study investigating romantic stress that looked at nondepressed youth who went through a recent breakup and were given 60mg of Griffonica Simplicifonia (12.8mg 5-HTP) twice a day for 6 weeks in an open-label study noted reductions in percieved romantic stress when measured at the 3 week mark with no further improvement at 6 weeks; there was no control nor placebo group in this study.[29]
Hi Ben. Have a groin problem which I have had for years and it just won’t go away it’s not a hernia or osteitis pubis I had an MRI and the specialist said they wouldn’t operate. I can still play sport but I’m just less agile and slower than normal and it takes a few days for the groin pain to go away after sport. Would tb500 help to heal it or would bpc157 or something else be better? Thanks :)
I had tennis elbow on both arms for over 3 years now. Had one surgery on the R, countless PRPs, and a stem cell treatment on both but still to no avail. Pain on the L never eased up and I just had my 3rd PRP booster injections yesterday after having my stem cells 2 months ago. So can you tell me if BPC 157 or TB 500 better suits my situation. Many thanks!
Research shows that co-administration with carbidopa greatly increases plasma 5-HTP levels.[46] However, several studies have reported that 5-HTP is effective even without a peripheral decarboxylase inhibitor (e.g. carbidopa).[47][unreliable medical source?] Other studies have indicated the risk of a scleroderma-like condition resulting from the combination of 5-HTP and carbidopa.[48]
