Kim found that when Americans who carry a particular version of the OXTR gene are more likely to turn to their friends for support when they are distressed. But Koreans react to social stress in a different way – for them, it’s less socially acceptable to turn to friends for support during tough times. And distressed Koreans who carry the same version of OXTR are less likely to seek support from their friends.

I broke my neck this year at C6-C7 facets. Started taking TB-500 immediately following the accident. I don’t sit still well and was back in the gym almost immediately, simply to not go stir crazy and pump the blood anyway I could. 8 weeks later I was hitting bodyweight overhead squats for reps with the jerk, 0 pain and completely stable spine. I’m in my late 30s. I eat well, sleep well, and drink a lot of water. I doubt I would have been as well off, had I not taken the TB.

Our nutrition team created these easy mix-and-match menus using the same guidelines that helped 5-HTP dieters lose weight at top speed during the University of Rome study. The idea here is simple: You’ll eat balanced meals that keep you feeling energized and awesome, but you’ll also watch portions so you’re not overeating out of habit. While using these menus, be sure to drink plenty of water and add any other zero-cal beverages you like. You’re also encouraged to season meals to your liking with unlimited herbs, spices, vinegar, mustard, and citrus juice. As always, get a doctor’s OK before trying any new plan.

Wonderful column. My expertise is the psychology of risk perception, and I have done some reading on oxytocin and trust (not the kind you want to boost in a bar with Liquid Trust – you can the stuff with pheromones – to boost THAT kind of trust). It turns out there is a high concentration of oxytocin receptors on the amygdala, the area of the brain where fear starts. As oxytocin levels go up, the ability of the amygdala to be warry and more mistrustful goes down. I describe this in Ch. 3 of How Risky Is It, Really? Why Our Fears Don’t Always Match the Facts. A few graphs of which are below. I wonder whether the influence of oxytocin on the amygdala might be connected with the finding of the study you write about.
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]
Three groups of mice were individually placed in cages with aggressive mice and experienced social defeat, a stressful experience for them. One group was missing its oxytocin receptors, essentially the plug by which the hormone accesses brain cells. The lack of receptors means oxytocin couldn't enter the mice's brain cells. The second group had an increased number of receptors so their brain cells were flooded with the hormone. The third control group had a normal number of receptors.
Dietary supplements containing 5-HTP are claimed to help promote feelings of happiness and general well-being as well as a wide range of other positives such as appetite control, reduced anxiety, and improved mood, sleep and feelings of relaxation. However, there is no conclusive evidence showing that it is effective, and there is no clear "therapeutic" dose of 5-HTP.
It is highly important to understand that MT2 itself does not protect skin from burning, tan protects your skin. Until some base tan is developed users should still take care not to over-expose skin to uv rays. Starting only with the amount of exposure that the user's skin can handle without burning. It should not take long before the user can handle longer exposures to strong sunlight without adverse effects.
In the hypothalamus, oxytocin is made in magnocellular neurosecretory cells of the supraoptic and paraventricular nuclei, and is stored in Herring bodies at the axon terminals in the posterior pituitary. It is then released into the blood from the posterior lobe (neurohypophysis) of the pituitary gland. These axons (likely, but dendrites have not been ruled out) have collaterals that innervate neurons in the nucleus accumbens, a brain structure where oxytocin receptors are expressed.[31] The endocrine effects of hormonal oxytocin and the cognitive or behavioral effects of oxytocin neuropeptides are thought to be coordinated through its common release through these collaterals.[31] Oxytocin is also produced by some neurons in the paraventricular nucleus that project to other parts of the brain and to the spinal cord.[32] Depending on the species, oxytocin receptor-expressing cells are located in other areas, including the amygdala and bed nucleus of the stria terminalis.

To pursue the sexual dysfunction agent, melanotan-II was licensed by Competitive Technologies to Palatin Technologies.[9] Palatin ceased development of melanotan-II in 2000 and synthesized, patented, and began to develop bremelanotide, a likely metabolite of melanotan-II that differs from melanotan-II in that it has a hydroxyl group where melanotan-II has an amide.[6][13] Competitive Technologies sued Palatin for breach of contract and to try to claim ownership of bremelanotide;[13] the parties settled in 2008 with Palatin retaining rights to bremelanotide, returning rights to melanotan-II to Competitive Technologies, and paying $800,000.[14]
Melanotan II first captured the public's imagination when the mainstream media briefly touted it as a Viagra-like panacea for middle-aged men. Norman Levine, a dermatologist who led the team that developed the drug, had first conducted experiments in which he darkened the pigments of frogs by injecting them with a hormone called Alpha MSH. After Melanotan II was modified for human use and put through clinical trials, Levine reported that "one very astute observer who took this drug told us that he was developing spontaneous erections."

Ultimately, this lack of literature on the drug best serves to illustrate the recklessness of Stephen Dank in committing to something so experimental in nature. Perhaps he was privy to anecdotal evidence the rest of us weren’t. The drug has been used by amateur athletes and bodybuilders, and reportedly in the equine industry. Nevertheless, any benefits are unsubstantiated, which lends to an exasperation shared by supporters as to why Dank would risk so much for a substance that potentially offers no advantage at all. As a supporter, I would have much preferred a drug that allowed us to hit a target inside 50.
5-HTP is converted by the body to serotonin, a chemical in the brain that plays an important role in mood, sleep, and appetite. Many prescription medications used for the treatment of depression increase serotonin concentrations in the brain. Because of 5-HTP's pathway to serotonin, it has appealed to researchers as well as the public as a "natural" alternative to antidepressants and treatment of depression, insomnia, migraines, obesity, and fibromyalgia.
In some studies that record appetite suppression with 5-HTP supplementation, nausea appears to also be reported at higher freqencies than placebo,[9] although some interventions note this as the only relevant side effect.[10] Short term studies tend to note that nausea persists throughout the study period[10] while those expanding beyond three weeks note that reports of nausea tend to decline at this time point.[9]

The biologically active form of oxytocin, commonly measured by RIA and/or HPLC techniques, is also known as the octapeptide "oxytocin disulfide" (oxidized form), but oxytocin also exists as a reduced straight-chain (non-cyclic) dithiol nonapeptide called oxytoceine.[120] It has been theorized that oxytoceine may act as a free radical scavenger, as donating an electron to a free radical allows oxytoceine to be re-oxidized to oxytocin via the dehydroascorbate / ascorbate redox couple.[121]

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.
“The study was double-blinded and was for two consecutive 6-wk periods. No diet was prescribed during the first period, a 5040-kJ/d diet was recommended for the second. Significant weight loss was observed in 5-HTP-treated patients during both periods. A reduction in carbohydrate intake and a consistent presence of early satiety were also found. These findings together with the good tolerance observed suggest that 5-HTP may be safely used to treat obesity.”
