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]

I’ve used powdered 5-HTP a couple times now, it doesn’t taste great and it’s resulted in an unpleasant stomach upset that lasted 45–60 minutes. For that reason I’ll likely not continue to use it. I did not find it’s effect on mood remarkable enough that I would want to put up with the stomach upset. My go to Nootropics for mood are Rhodiola and Phenibut and my go to Biohacks for mood are meditation and no fap, I don’t feel the need to use a whole lot more mood promoting strategies.

Half the group of burned volunteers got a whiff of Eau de Oxytocin, half got a sniff of Eau de Placebo. Those who sniffed the oxytocin were more trusting and ready to invest with an anonymous trustee a second time than were the placebo-exposed subjects. And when they were asked “Do you want to try this again?” the oxytocin-treated volunteers responded more quickly than the volunteers who hadn’t gotten the nose full of Trust Spray.6

Thymosin beta-4 is a very large molecule. In fact, it is so large that it cannot fit entirely into the receptor. Different sections of the molecule have different activities. TB-500 is the part of thymosin beta-4 hormone which promotes the most useful effects (overall healing, repair, new blood and muscle cells). For medical applications it is more practical to use the TB-500 instead of the entire Thymosin Beta-4 protein.

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]
5-HTP, along with other L-Tryptophan supplements, have been implicated in the flu-like, potentially fatal Eosinophilic Myalgia Syndrome. This syndrome was initially tied to  impurities - Amino Acids called "Peak E" and "Peak X" - which were present in these products because of poor manufacturing processes by a single major supplier. Some people reject this idea and believe that the syndrome is caused by an excess of tryptophan itself (10, 11).
It was also shown recently that delivery of Fgfs by release from peptide nanofibers, a gradual local delivery system, can increase neovascularization and reduce in-farct size in the ischemic rodent heart (Engel et al., 2006). Related to this, zebrafish have a natural ability to synthesize Fgfs after myocardial injury, a signal that appears to recruit Fgf receptor-expressing epicardial-derived cells toward regenerating muscle (Lepilina et al., 2006). Thus, what has been and what will be discovered about zebrafish heart regeneration is quite likely to illuminate possible strategies for enhancing regeneration in the mammalian heart (see Chapter 14.4).
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!”
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.”
In the end, despite three years of intense scrutiny, the drug at the centre of the investigation remains poorly understood. In this regard, it could serve as a reflection of the whole ordeal. Everyone has an opinion, often voiced with authority and conviction. The reality is that much of this complex narrative continues to be a mystery. Many would have been well served by the humble words of the Socratic paradox – “I know that I know nothing”.
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.
Second, 5-HTP can cause serious drug interactions with many medications, especially those used to treat depression. Because antidepressants generally work by increasing serotonin in the brain, 5-HTP could combine with these medications to cause high concentrations of serotonin. Having too much serotonin can lead to serotonin syndrome, a serious condition characterized by dangerously high heart rate, blood pressure, and temperature. 5-HTP can interact with other classes of drugs, like migraine and pain medications, that also affect serotonin concentrations.
Thymosin beta 4, developed by RegeneRx Biopharmaceuticals as a pharmaceutical for the healing of wounds, is a synthetic version of the natural peptide. As Dr. Allan Goldstein emphasizes, “Tb4 represents a new class of wound healing compounds. It is not a growth factor or cytokine, but rather exhibits a number of physiological properties which include the ability to sequester and regulate actin, its potent chemotactic properties. . . and its capability to downregulate a number of inflammatory cytokines that are present in chronic wounds.” When a wound heals there are many growth factors produced in the area so that additional factors, such as those currently on the market for wound healing, may help but are not necessarily lacking. Tb4 treatment, however, adds a new dimension to wound repair by providing cells with actin as needed, for cell migration, replication and differentiation.
For depression: Most commonly, 150-800 mg daily is taken for 2-6 weeks. These doses are sometimes divided up and administered as 50 mg to 100 mg three times a day. Sometimes the dose starts out low and steadily increases every 1-2 weeks until a target dose is reached. Less commonly, higher doses are used. In one study, the dose is steadily increased up to 3 grams per day.
For decades, 5-HTP has been recognized as important to appetite regulation. Higher levels of serotonin are linked to diminished appetite. Keeping serotonin levels from dipping can help keep appetite in check, and may help reduce cravings for carbohydrates. As a serotonin booster, 5-HTP may help to suppress appetite. Research indicates that 5-HTP may be effective in helping people who are overweight or obese lose weight.
