“I didn’t think it would be that bad honestly, but since I weight lift multiple times a weak, this supplement is doing me more harm than good. On a typical weight lifting day my workout is split into 5 sections. After taking 5-htp the night before I barely have enough energy to get through 1 section, and that is a serious problem, because of this I am quitting 5-htp all together.”
Autism. A 1998 study found significantly lower levels of oxytocin in blood plasma of autistic children. A 2003 study found a decrease in autism spectrum repetitive behaviors when oxytocin was administered intravenously. A 2007 study reported that oxytocin helped autistic adults retain the ability to evaluate the emotional significance of speech intonation.
Melanotan II is a synthetic analogue of the α-melanocyte stimulating hormone (α-MSH). α-MSH is a melanocortin I receptor agonist which has a role in human pigmentation by stimulating production of eumelanin. As melanotan II is a non-specific melanocortin receptor agonist, it has been reported to cause toxicity effects involving the many physiological systems affected by the receptors.
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.
In the experiments, an epithelial wound was made in the corneas of sedated rats. A Tb4 solution was applied at several concentrations to the injured eyes in one group of rats while another group was treated with a solution without Tb4. Following 12, 24 and 36 hours, the eyes were tested by microscopic observation for epithelial growth over the injured site. Investigators found the Tb4 accelerated corneal wound repair at doses of Tb4 similar to those found to repair skin wounds. When tested 24 hours after treatment, the rate of accelerated repair was proportional to the concentration of Tb4, with the highest dose (25 microgram) showing a threefold acceleration of epithelial cell migration, compared to untreated. Treatment with Tb4 showed anti-inflammatory effects, helping resolve the injury. An application to human cells in a model of human corneal cells in culture showed that Tb4 enhanced epithelial cell migration in vitro.
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!
5-HTP is necessary for the proper functioning of your body. It is decarboxylated in the brain and liver to produce serotonin, a neurotransmitter. Serotonin is involved in the communication between nearly all of our 40 million brain cells, and is also found in large quantities in the cells of the gut, and in blood platelets. Because of its widespread distribution through the cells of the body, Serotonin is believed to have a large number of psychological and physiological effects. It has been used to treat conditions as diverse as obesity, depression, fibromyalgia, insomnia, and headaches, with varying success.

There are several layers in the skin; the outer epidermis and beneath it the dermis and the subcutaneous layer. Cells in the epidermis include keratinocytes, its major cell type, that move continuously from the lower basal layer where they are formed by cell division. Other cells in the epidermis are the melanocytes that synthesize pigment and transfer it to the keratinocytes, giving our skin its color, and a wide variety of immune cells that maintain immune surveillance and secrete substances called cytokines, like interleukin 1 and 2, which are active in inflammation. The dermis contains connective tissue, mainly collagen, blood vessels, various types of immune white cells and fibroblasts.
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).
Advice & Tips: 5-HTP is a serotonin precursor. Serotonin is well-known as a hormone that affects one's mood in a positive way, but it is probably less-well known that it increases intestinal motility. It has worked magic for my symptoms. I am completely regular now, and the majority of my days are good days, whereas before I began taking it the majority of my days were bad days that began with symptoms of constipation and intestinal pain or discomfort. For me, at least, this is not a prescription. I began taking 5-HTP after my fiancee'--who had already been taking it to help her mood and, primarily, her difficulty sleeping through the night--learned it can be helpful when taken for gastrointestinal motility, and I began taking it myself shortly after that (and felt its effects almost immediately). Although not entirely unexpected, my slightly enhanced good moods are a nice side benefit of taking the supplement. I do get some very mild undesirable side effects, especially during mid-day when I take twice my morning and evening dose of 100 mg. Sometimes my face feels hot and flushes fairly noticeably--and this may be intensified with eating--but those symptoms subside within probably 30 minutes or less.
These proteins became of interest in neurobiology with the finding that in the nudibranch (sea slug) Hermissenda crassicornis, the protein Csp24 (conditioned stimulus pathway phosphoprotein-24), with 4 repeats, is involved in simple forms of learning: both one-trial enhancement of the excitability of sensory neurons in the conditioned stimulus pathway, and in multi-trial Pavlovian conditioning. The phosphorylation of Csp24, in common with post-translational modifications of a number of cytoskeleton-related proteins may contribute to actin-filament dynamics underlying structural remodeling of responsive cells.
Affecting generosity by increasing empathy during perspective taking. In a neuroeconomics experiment, intranasal oxytocin increased generosity in the Ultimatum Game by 80% but has no effect in the Dictator Game that measures altruism. Perspective-taking is not required in the Dictator Game, but the researchers in this experimental explicitly induced perspective-taking in the Ultimatum Game by not identifying to participants which role they would be in.13
Melanotan II non-selectively mimics the action of melanocortin peptides. These are natural hormones involved with pigmentation, energy homeostasis, sexual functioning, the immune system, inflammation, and the cardiovascular system. Much like melanotan I (afamelanotide), melanotan II stimulates the production of eumelanin, causing the skin to go darker (tanning).

Treatment with thymosin beta 4 (Tβ4) reduces infarct volume and preserves cardiac function in preclinical models of cardiac ischemic injury. These effects stem in part from decreased infarct size, but additional benefits are likely due to specific antifibrotic and proangiogenic activities. Injected or transgenic Tβ4 increase blood vessel growth in large and small animal models, consistent with Tβ4 converting hibernating myocardium to an actively contractile state following ischemia. Tβ4 and its degradation products have antifibrotic effects in in vitro assays and in animal models of fibrosis not related to cardiac injury. This large number of pleiotropic effects results from Tβ4’s many interactions with cellular signaling pathways, particularly indirect regulation of cellular motility and movement via the SRF–MRTF–G-actin transcriptional pathway. Variation in effects and effect sizes in animal models may potentially be due to variable distribution of Tβ4. Preclinical studies of PK/PD relationships and a reliable pharmacodynamic biomarker would facilitate clinical development of Tβ4.
Some differences in cardiac anatomy exist between mammals and teleosts. The zebrafish ventricle has a thin wall of compact muscle surrounding a much larger compartment of myofibers organized into elaborate trabeculae. It is intriguing that this structure is very similar to that of the embryonic mammalian ventricle prior to its septation and fusion of trabeculer myofibers into a thick, vascularized wall (Sedmera et al., 2000). That the mammalian heart has a more differentiated, contractile anatomy is apparent not only in gross cardiac structure, but also in cellular features. Teleost cardiomyocytes are 2–10 times smaller, mononucleated, have a greatly-reduced sarcoplasmic reticulum and lack the T-tubule system found in skeletal muscle and mammalian cardiac muscle (Farrell, 1992). One might speculate that the teleost heart is better designed for growth and regeneration, while the mammalian heart is better designed for sheer contractile force. Nevertheless, none of the mentioned differences between lower and higher vertebrate hearts preclude the idea that the mammalian heart could be stimulated to regenerate, especially if that regeneration is due to mobilization of a progenitor cell population.
Oxytocin is a hormone that also acts as a neurotransmitter in the brain. Some popular media have incorrectly labeled it the “love hormone,” because it is associated with good feelings and emotions. But its role in the body is much more complex than that. It is not a bliss or hug hormone, but it does appear to be connected to human emotions and the regulation of childbirth and breast-feeding.
Although research has shown that good communication predicts relationship success, successful communication in couples therapy won’t ensure that partners stay together. The goal is to help the two people understand each other’s point of view and come to a mutual decision, even if it’s to break up. “If people are not connected at all, then oxytocin is not going to force that connection,” Guastella says.
5-HTP works in the brain and central nervous system by increasing the production of the chemical serotonin. Serotonin can affect sleep, appetite, temperature, sexual behavior, and pain sensation. Since 5-HTP increases the synthesis of serotonin, it is used for several diseases where serotonin is believed to play an important role including depression, insomnia, obesity, and many other conditions.
