Supplements haven't been tested for safety and due to the fact that dietary supplements are largely unregulated, the content of some products may differ from what is specified on the product label. Also keep in mind that the safety of supplements in pregnant women, nursing mothers, children, and those with medical conditions or who are taking medications has not been established. You can get tips on using supplements, but if you're considering the use of 5-HTP supplements, talk with your primary care provider first. Self-treating a condition and avoiding or delaying standard care may have serious consequences.
20 patients (nine from the 5-HTP group and 11 from the Placebo group) completed the study. Brain tryptophan availability in diabetic patients was significantly reduced when compared to a group of healthy controls. Patients receiving 5-HTP significantly decreased their daily energy intake, by reducing carbohydrate and fat intake, and reduced their body weight.”
In 1989, a nationwide outbreak sickened over 1500 people and caused at least 30 deaths in the US. The outbreak was characterized by severe muscle pain and high white blood cell count. The culprit was later determined to be tryptophan supplements made by a specific manufacturer that were thought to be contaminated. Shortly thereafter, the FDA recalled and banned all forms of tryptophan supplements. In the meantime, an alternative supplement called 5-hydroxytryptophan (5-HTP), which is a chemical byproduct of tryptophan, was introduced as an alternative and has since become popular.
The pore-forming subunit of the cardiac sodium channel Nav1.5 encoded by SCN5A is a critical determinant of myocardial excitability and conduction. Loss-of-function mutations in SCN5A can clinically manifest as progressive cardiac conduction disorders or as arrhythmic syndromes, such as Brugada syndrome. In addition to electrophysiological dysfunction, SCN5A mutations are also associated with myocardial fibrosis manifesting as global cardiomyopathy. In a 10-year old child exhibiting Brugada syndrome, the mutation SCN5AE555X was discovered. Therefore, cardiac sodium channelopathy pig models were generated by homologous recombination in the genetic background of outbred Yucatan minipigs via SCNT exhibiting the orthologous porcine heterozygous mutation SCN5AE558X. The heterozygous mutant animals were viable and fertile, and showed no sudden death over a 2-year monitoring period. They showed reduced SCN5A protein expression, which resulted in diminished total sodium conductance. The heterozygous mutant hearts showed slowed conduction and increased susceptibility for ventricular arrhythmias in the absence of structural defects of the myocardium or specialized conduction system. In total, a novel animal model was established for understanding the mechanisms linking sodium channel dysfunction to cardiac pathophysiology (Park et al., 2015b).

Exposure to ultraviolet (UV) light prompts an increased release of Alpha-MSH, which in turn stimulates the production of melanin in the skin. The more melanin produced the greater pigmentation level becomes, making the skin progressively darker and tan lasts significantly longer. This makes Melanotan peptide unique, people do not require as much exposure to UV light to produce more melanin, very attractive for people wishing to develop greater tanning of the skin in fastest way possible.
Low oxytocin levels have been linked to autism and autistic spectrum disorders (e.g. Asperger syndrome) – a key element of these disorders being poor social functioning. Some scientists believe oxytocin could be used to treat these disorders. In addition, low oxytocin has been linked to depressive symptoms and it has been proposed as a treatment for depressive disorders. However, there is not enough evidence at present to support its use for any of these conditions.

Social behavior[66][111] and wound healing: Oxytocin is also thought to modulate inflammation by decreasing certain cytokines. Thus, the increased release in oxytocin following positive social interactions has the potential to improve wound healing. A study by Marazziti and colleagues used heterosexual couples to investigate this possibility. They found increases in plasma oxytocin following a social interaction were correlated with faster wound healing. They hypothesized this was due to oxytocin reducing inflammation, thus allowing the wound to heal more quickly. This study provides preliminary evidence that positive social interactions may directly influence aspects of health.[112] According to a study published in 2014, silencing of oxytocin receptor interneurons in the medial prefrontal cortex (mPFC) of female mice resulted in loss of social interest in male mice during the sexually receptive phase of the estrous cycle.[113] Oxytocin evokes feelings of contentment, reductions in anxiety, and feelings of calmness and security when in the company of the mate.[101] This suggests oxytocin may be important for the inhibition of the brain regions associated with behavioral control, fear, and anxiety, thus allowing orgasm to occur. Research has also demonstrated that oxytocin can decrease anxiety and protect against stress, particularly in combination with social support.[114] It is found, that endocannabinoid signaling mediates oxytocin-driven social reward.[115]
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.
Melanotan 2 works by stimulating the release of the pigment melanin from the skin. Less UV exposure is necessary with Melanotan 2 compared to “normal tanning”, and the tan that occurs with tanning injections is deeper and longer lasting than an individual’s “normal tan”. Melanotan works best (has the most noticeable effects) on people with fair skin tones.
In 19 obese females given either placebo or 8mg/kg (weight not actually given, only BMI between 30-40 for women) daily for 5 weeks without any concurrent dietary recommendations, 5-HTP treatment was associated with a decrease in appetite and food intake (resulting in weight loss) without significantly affecting mood state.[9] This study noted that food intake was reduced from an average of 2,903kcal to 1,819kcal (62% of baseline) while placebo only reduced calories to 80%, and the 0.5kg weight loss in placebo was outperformed by a near 1.5kg loss in 5-HTP. These weight loss effects have been noted with 750mg 5-HTP over 2 weeks in overweight diabetics[10] and over 12 weeks in obese persons given 900mg 5-HTP daily (58% of baseline intake); this latter study had a 6 week trial without a diet (in which significant weight loss was only noted at week 6) followed up by coadministration with a diet where weight loss proceeded to reach an additional 3.3kg over the subsequent 6 weeks;[11] this latter study is duplicated in Medline.[12]
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.

Melanotan II has reported toxicity effects from therapeutic and overdose exposures including: renal dysfunction, rhabdomyolysis, sympathomimetic overdrive, change in size and pigmentation of pre-existing moles, rapid increase in the number of new moles associated with causing melanomas, posterior reversible encephalopathy syndrome, refractory priapism, stretching and yawning syndrome, shortness of breath, chest pain, abdominal cramping and pain, dizziness and lethargy. XXXXXX alone has received 28 calls about melanotan II since 2006.

A and B; Mouse BMMs were cultured with 200 μM H2O2 and indicated concentrations of Tβ4 peptide in the presence of M-CSF (30 ng/mL) and RANKL (100 ng/mL). C and D; PDLCs were co-cultured with mouse BMMs in the presence of M-CSF, RANKL, 200 μM H2O2, and indicated concentrations of Tβ4 peptide. To monitor osteoclast differentiation, both TRAP activity and the number of TRAP multinucleated cells were examined. * Statistically significant difference compared with 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.


It should be noted that, anecdotally, 5-HTP is said to reduce cravings for carbohydrates in particular. The serotonergic (related to serotonin) system plays a role in macronutrient selection particular in obese persons with a craving for carbohydrates[13] and enhancing serotonergic transmission is known to reduce these cravings.[14] Beyond this, depressed serotonergic tranmission (hypothalamus) is also implicated in increased eating and reduced satiety in general.[15]
Oxidative stress is characterized by an accumulation of ROS and plays a key role in the progression of periodontal diseases [24]. Damage of tissues in inflammatory periodontal disease can be mediated by ROS resulting from the physiological activity of PMN during the phagocytosis of periodontopathic bacteria [27]. In addition, LPS from Porphyromonas gingivalis as well as hypoxia induces a NOX4-dependent increase in H2O2 release in PDLCs [28]. Furthermore, ROS such as H2O2 are small, diffusible, and ubiquitous molecules, can affect human PDLCs and gingival fibroblasts cell injury indirectly by enhancing pro-inflammatory factors such as cytokines, NO, PGE2, and ROS [29–31]. This ROS is known to stimulate osteoclast differentiation and participate in early signaling events associated with osteoclast activation for bone resorption [32]. Since LPS from P. gingivalis increases oxidative stress in PDLCs and contributes to periodontitis [28], human PDLCs treated with H2O2 may serve as an in vitro model relevant to periodontitis.
"By understanding the oxytocin system's dual role in triggering or reducing anxiety, depending on the social context, we can optimize oxytocin treatments that improve well-being instead of triggering negative reactions," said Jelena Radulovic, the senior author of the study and the Dunbar Professsor of Bipolar Disease at Northwestern University Feinberg School of Medicine. The paper was published July 21 in Nature Neuroscience.

Like I said, it’s amazing stuff. And it shouldn’t come as a surprise that it affects that amazing part of your brain so intimately involved in keeping you safe…the amygdala. Remember, trust has a lot to do with survival among social animals who depend on each other for safety and protection. Show someone an untrustworthy face, and the amygdala is one of two areas that become more active than anywhere else in the brain.7 It is apparently programmed for reading trust just as it is for snakes or spiders.

Studies on diabetic rats indicated significant increases in the amount of collagen and in tensile strength of light-treated wounds over controls (Stadler et al., 2001; Reddy et al., 2001). In combination with hyperbaric oxygen, light-treated skin wounds in rats closed faster (Yu et al., 1997), an effect that was associated with a more uniform rise and fall in VEGF and FGF-2 instead of the sharp peaks at day four and subsequent rapid drop-off observed in control wounds (Whelan et al., 2001). In vitro, proliferation of mouse fibroblasts was increased by over 150% and that of human epithelial cells by 155–171% (Whelan et al., 2001). Whelan et al. (2001) also reported that wound-healing time was decreased by 50% aboard a submarine, where the atmosphere is lower in oxygen and higher in carbon dioxide, and that children suffering from oral mucositis as a result of chemotherapy experienced a 47% reduction in pain. Recently, however, a randomized trial using a 980 nm diode laser to treat venous leg ulcers of 18 patients indicated no difference in reduction of ulcer size compared to the 16 control patients (Leclere et al., 2010).
Ingroup bonding: Oxytocin can increase positive attitudes, such as bonding, toward individuals with similar characteristics, who then become classified as "in-group" members, whereas individuals who are dissimilar become classified as "out-group" members. Race can be used as an example of in-group and out-group tendencies because society often categorizes individuals into groups based on race (Caucasian, African American, Latino, etc.). One study that examined race and empathy found that participants receiving nasally administered oxytocin had stronger reactions to pictures of in-group members making pained faces than to pictures of out-group members with the same expression.[62] This shows that oxytocin may be implicated in our ability to empathize with individuals of different races and could potentially translate into willingness to help individuals in pain or stressful situations. Moreover, individuals of one race may be more inclined to help individuals of the same race than individuals of another race when they are experiencing pain. Oxytocin has also been implicated in lying when lying would prove beneficial to other in-group members. In a study where such a relationship was examined, it was found that when individuals were administered oxytocin, rates of dishonesty in the participants' responses increased for their in-group members when a beneficial outcome for their group was expected.[63] Both of these examples show the tendency of individuals to act in ways that benefit those considered to be members of their social group, or in-group.

Thymosin beta 4 accelerated skin wound healing in a rat model of a full thickness wound where the epithelial layer was destroyed. When Tb4 was applied topically to the wound or injected into the animal, epithelial layer restoration in the wound was increased 42% by day four and 61% by day seven, after treatment, compared to untreated. Furthermore, Tb4 stimulated collagen deposition in the wound and angiogenesis. Tb4 accelerated keratinocyte migration, resulting in the wound contracting by more than 11%, compared to untreated wounds, to close the skin gap in the wound. An analysis of skin sections (histological observations) showed that the Tb4 treated wounds healed faster than the untreated. Proof of accelerated cell migration was also seen in vitro, where Tb4 increased keratinocyte migration two to three fold, within four to five hours after treatment, compared to untreated keratinocytes.

So far, few studies have definitively linked autism to problems in oxytocin signalling. Some of the clearest evidence emerged in February, from a team led by neurogeneticist Daniel Geschwind of the University of California, Los Angeles. The group showed that mice that lacked a working copy of the Cntnap2 gene — which has been implicated in a small subset of human autism cases — had fewer oxytocin-containing neurons in the hypothalamus and socialized less with other mice than did control mice15. After receiving doses of oxytocin every day for two weeks, the mice behaved normally again. “Until this, there was no evidence that there was a subtype of autism that had to do with oxytocin deficits,” Geschwind says.
Traumatic brain injury (TBI) remains a leading cause of mortality and morbidity worldwide. No effective pharmacological treatments are available for TBI because all Phase II/III TBI clinical trials have failed. This highlights a compelling need to develop effective treatments for TBI. Endogenous neurorestoration occurs in the brain after TBI, including angiogenesis, neurogenesis, synaptogenesis, oligodendrogenesis and axonal remodeling, which may be associated with spontaneous functional recovery after TBI. However, the endogenous neurorestoration following TBI is limited. Treatments amplifying these neurorestorative processes may promote functional recovery after TBI. Thymosin beta4 (Tβ4) is the major G-actin-sequestering molecule in eukaryotic cells. In addition, Tβ4 has other properties including anti-apoptosis and anti-inflammation, promotion of angiogenesis, wound healing, stem/progenitor cell differentiation, and cell migration and survival, which provide the scientific foundation for the corneal, dermal, and cardiac wound repair multicenter clinical trials. Here, we describe Tβ4 as a neuroprotective and neurorestorative candidate for treatment of TBI.
However, the Food and Drug Administration and its equivalents in other countries have issued repeated advisory notices about Melanotan II, urging consumers to stop using and purchasing this unapproved product. David Carter of the United Kingdom's Medicines and Healthcare Products Regulatory Agency was unequivocal in his denunciation, warning would-be buyers against being "fooled into thinking that Melanotan offers a shortcut to a more even tan." Liverpool John Moores University researcher Michael Evans-Brown cautioned that the peptide may be linked to dyspepsia and various cardiovascular problems, such as increases in blood pressure, while others have noted it appears to stimulate the growth of moles on the body.
5-HTP is very reliable in increasing serotonin levels. 5-HTP is actually used as a clinical test to judge the potency of drugs that affect serotonin levels (by pairing an experimental drug with 5-HTP to induce 'serotonin syndrome', or serotonin toxicity, one can see how much that drug exacerbates serotonin biosynthesis or bioavailability by seeing how much of a 5-HTP dose is required to induce the syndrome; the lower dose indicative of higher drug potency). This test is known as the 5-HTP induced syndrome test.[8]
This is a great product, I have been having digestive problems after 13 major surgeries and suffering from Crohn's Disease my whole life. Currently I can only tolerate a liquid diet. Was very depressed, found this and started taking it and it has made a HUGE difference to my life. Only have very mild depression symptoms now, and sleep better at night. Bought the powder to get the dose right, looks like 100mg suits my 50 kg frame. Only bad thing is the packaging. The 10 grams of powder is lost in the large packet, very hard to get it out and measure the same dose every night. I purchased miniature measuring spoons from ebay and they make life much easier. Sort out the correct spoon for your dosage with the scales then off you go. Can be tricky getting it in and out of the bag, often get powder everywhere, but usually just lick it off. A pill container would work much better for this power.
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.

It’s a compound that the body needs in order to make serotonin, which is our main “happiness hormone.” Per Dr. Oz, 5-HTP floods the brain with serotonin and helps minimize stress, sadness, anger, and anxiety. “5-HTP targets specific emotions that drive us to overeat,” Dr. Bhatia explains. And as she already mentioned, 5-HTP also reduces physical hunger pangs and emotional cravings. Ideally, the body makes its own 5-HTP from the amino acid tryptophan, found in foods like turkey and bananas. (Why not just eat more turkey or take a tryptophan supplement? If you struggle with mood or weight, it can be a sign that your body has trouble converting tryptophan to 5-HTP.) Besides making it yourself, the only other way to get 5-HTP is from a supplement. One we like is the BRI 5-HTP Supplement ($16 for 120 capules, Amazon).
Young says that the oxytocin field would benefit from closer collaboration between basic and clinical researchers. If basic scientists can work out how oxytocin helps the brain to process social stimuli, then that might help in the design of stimuli — in the form of behavioural therapies — that could be given alongside the hormone to change behaviour, just as oxytocin and pup calls together affect virgin mice. “I think in the future these two branches need to have more communication,” Young says.
Outside the brain, oxytocin-containing cells have been identified in several diverse tissues, including in females in the corpus luteum[34][35] and the placenta;[36] in males in the testicles' interstitial cells of Leydig;[37] and in both sexes in the retina,[38] the adrenal medulla,[39] the thymus[40] and the pancreas.[41] The finding of significant amounts of this classically "neurohypophysial" hormone outside the central nervous system raises many questions regarding its possible importance in these different tissues.

But long before that, say researchers, oxytocin could use a rebranding. “It doesn't induce love; it doesn't induce massive amounts of trust,” Guastella says. “The problem we've got ourselves into is that we're trying to look for a simple answer: either oxytocin does or does not work in a patient population, or it does or does not enhance a certain social process.”
Though it may be unlikely to form part of any official psychiatric programme in the UK, Phil Cowen, Professor of Psychopharmacology at Oxford University, admitted that there are various groups for whom it could be helpful. "About half of people with severe depression never see a doctor anyway, so it's reasonable to think it's fine for them to treat themselves with something like a supplement. Perhaps if you had mild symptoms, a smaller dose would be helpful. I'd also prefer to prescribe things like exercise or computer-based CBT if it's that stage, though. But depression and anxiety is very different between people, that's important to keep in mind. No treatment is the same for anyone."

Combined treatments of 5-HTP and SSRI seem to have strong synergistic effects on serotonin levels in rats and humans so that some clinicians recommend the use of slow-released 5-HTP in combination with SSRIs (R, R2, R3). However, additional clinical trials are required to demonstrate the safety and effectiveness of this approach, and combinations of 5-HTP and medications should only be used under medical supervision.
