Due to its molecular structure and low molecular weight, TB-500 is very versatile, mobile and possesses the ability to travel long distances through tissues. This means that when targeting injured areas (chronic or acute), TB-500 has the ability to circulate through the body and “find” those areas of injury in order to enhance the healing or growth process. Many users have also noted the added benefits of improved flexibility, reduced inflammation in tendons, re-growth of lost hair, and darkening of grayed hair.
 Don't be surprised.  A lot of people haven't heard of Melanotan.  Melanotan is a tanning peptide that stimulates the production of melanin in the body to foster a deep, natural tan.  This is the body's way of protecting itself from too much sun exposure by increasing the level of melanin in the body.  Melanin is your body's natural response to UV damage.  The end result is a darkening of the skin.
It has been shown that oxytocin differentially affects males and females. Females who are administered oxytocin are overall faster in responding to socially relevant stimuli than males who received oxytocin.[75][86] Additionally, after the administration of oxytocin, females show increased amygdala activity in response to threatening scenes; however, males do not show increased amygdala activation. This phenomenon can be explained by looking at the role of gonadal hormones, specifically estrogen, which modulate the enhanced threat processing seen in females. Estrogen has been shown to stimulate the release of oxytocin from the hypothalamus and promote receptor binding in the amygdala.[86]

5-HTP has been shown in scientific studies to promote relaxation and alleviate stress and anxiety. The relaxation and anti-anxiety properties of 5-HTP appear to come from its ability to elevate levels of serotonin. Research has demonstrated that 5-HTP may reduce the risks of panic attacks and symptoms of panic, as well as anxiety and emotional stress. Research also indicates 5-HTP may be effective in helping to alleviate depression.
In mammals, many mysteries remain. Oxytocin is difficult to measure reliably in the brain, making it hard to know exactly where, when and how much is normally released; nor do scientists understand precisely how it works to alter behaviour. “What we need to start thinking about is the more fundamental role that oxytocin plays in the brain,” Young says. The determination to find out has been strengthened by a growing move in neuroscience to characterize circuits that are important in brain operations. “That's the level that's critical for understanding how the brain is regulating behaviour,” says Thomas Insel, director of the US National Institute of Mental Health in Bethesda, Maryland, who has studied oxytocin in voles.

In the ER, the patient's heart rate was elevated, she was sweaty, and had some muscle spasms. The physician in the ER called Poison Control for guidance. Poison Control indicated that a drug interaction between 5-HTP and Zoloft was a likely cause of the patient's symptoms because they were consistent with a rare but serious condition (serotonin syndrome) that occurs when serotonin concentrations in the brain are too high. Poison Control recommended a sedative to decrease the patient's heart rate and improve the other symptoms. 

If you’re looking for hard proof that taking 5-HTP to lose weight works, we’ve got it: In a University of Rome study, obese women who took 5-HTP began eating between 1,000 to 2,000 fewer calories per day. And even as their caloric intake plummeted to a level that would leave many dieters irritable, serotonin was soothing these ladies — and not one reported hunger or diet crankiness. Further boosting spirits: The supplements quadrupled their weight loss, compared to folks given a placebo pill. “They ate a lot less than they normally would because it was easy for them,” Dr. Bhatia notes. Hearing about such an easy way to lose weight might be enough to inspire you to try the supplement for yourself. So, we went ahead and rounded up everything you need to know to get started.

In humans, the Tβ4 gene TMSB4X is localized to the X chromosome at Xq21.3–q22 (). The Tβ4 cDNA open reading frame contains an initial methionine codon followed by a codon for the N-terminal serine and, although cells secrete a certain amount of Tβ4, there is no hydrophobic signal sequence. The initial methionine residue of the nascent Tβ4 polypeptide is removed and the N-terminal serine residue is often acetylated in the cells.


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.
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.
About three months after quitting, I did have a major relapse, which was falling back into old habits for about two weeks. And the whole time I knew what was happening, I knew how dangerous it was, but I couldn't stop myself. I felt like I couldn't connect to anyone without drinking. I couldn't talk to my friends, I couldn't be open and honest with anybody in my life without already having had a few drinks. It was a really disconnected, really unpleasant feeling. That's what I couldn't sit with and I couldn't cope with that feeling, so I went back to drinking.
RegeneRx is continuing with pre-clinical research, in collaborative arrangements with the National Institutes of Health, accumulating data on the effects of Tb4 and aiming for an IND application (Investigational New drug App-lication) to proceed with clinical studies. Phase I clinical trials will determine the ability of Tb4 to repair ulcers in diabetic patients and to reduce inflammation and accelerate recovery from burns and abrasions to the cornea.
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.
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]
