Even if you did look after yourself adequately and monitor the amount of 5-HTP you were taking, it doesn't appear to be a permanent or lasting solution. A couple of the doctors talked about something that comes up time and time again with long-term SSRI use: a dissipating effect, meaning they can feel less and less effective over time. It seems that people may have the same problem with 5-HTP. "If you push on your biochemistry hard enough, it may downregulate," Dr Paddock explained. "If you're taking SSRIs your body may downregulate the amount of serotonin it puts out so you get waning effects over time. It's similar with 5-HTP. There may be a certain level of serotonin your body is keeping you at and if you raise it or push it, your body then may say, 'Okay, we're above the set point, let's then raise that point again.'"
There have been some side effects reported while using Melanotan 2, typically these effects appear during the first few days of dosing and will become increasingly less obvious as the body adjusts to the peptide. These effects include: nausea, appetite loss, drowsiness and increased sex drive. In order to combat nausea, an anti-histamine can be taken when injecting until the body gets used to it. But most common way to deal with this is to inject Melanotan before bed, this is also beneficial to combat any drowsiness.
A later experiment by another group took it a step further. This time the volunteers were told how they did, and in half of the cases, they learned that the trustee had burned them and kept the money. The volunteers who were burned were asked whether they wanted to try again. What would you do? This would be like getting that spam from the Nigerian Prince a second time and sending him $5,000 again, right?
Animal studies have found high levels of both stress and oxytocin in voles that were separated from other voles. However, when the voles were given doses of oxytocin, their levels of anxiety, cardiac stress, and depression fell, suggesting that stress increases internal production of the hormone, while externally supplied doses can help reduce stress.

Biopolymers. 41 (6): 623–34. doi:10.1002/(SICI)1097-0282(199705)41:6<623::AID-BIP3>3.0.CO;2-S. PMID 9108730. The thymosin is β9, bovine orthologue of human β10. Stabilised by organic solvent, the structure was determined by NMR. (Free β-thymosins lack a stable fold in solution)
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.

Researchers often investigate the effects of hormones on behavior in laboratory experiments with student subjects. Some studies show that when you give people oxytocin they become more generous and trusting. In others that administer testosterone to men, the opposite happens. The strength of such studies is that they can demonstrate cause and effect – the behavior change only occurs in subjects receiving hormones, not in those who get a placebo. But this research has weaknesses as well: it often focuses on single hormones, ignoring their potential interactions, and behavior is measured with highly artificial tasks.
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.
Do not fall for the easier methods of using MT-2, injections is the only proper way of using this peptide. Many Internet suppliers will sell things like nasal sprays, pre-mixed peptide, oral pills and powders, they simply don't work, if they did no one would use injections, right? There are a some positive reports of nasal spray experience, however its not very cost effective as peptide molecules in this form are large and difficult to pass the nasal membrance, there is some effect, but its minor comparable to injection route where absorption rate is 100%. Similarly, pills of this type are also quite useless because enzymes within the stomach will render the peptide inert.
In a study measuring oxytocin serum levels in women before and after sexual stimulation, the author suggests it serves an important role in sexual arousal. This study found genital tract stimulation resulted in increased oxytocin immediately after orgasm.[105] Another study reported increases of oxytocin during sexual arousal could be in response to nipple/areola, genital, and/or genital tract stimulation as confirmed in other mammals.[106] Murphy et al. (1987), studying men, found oxytocin levels were raised throughout sexual arousal with no acute increase at orgasm.[107] A more recent study of men found an increase in plasma oxytocin immediately after orgasm, but only in a portion of their sample that did not reach statistical significance. The authors noted these changes "may simply reflect contractile properties on reproductive tissue".[108]
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."
But returning hunters also need to share meat with their families and friends; this is where oxytocin comes into play. It can help overcome the potentially negative social effects of testosterone. Men who were absent for longer seem to need more oxytocin to reconnect with their families; it seems that absence does indeed make the heart grow fonder, via an oxytocin blast.

Skin damage and aging are induced to a large extent by free radicals from the sun and environmental pollutants and from oxidants produced during infection and inflammation. Lipid peroxidation of membranes and increased inflammatory substances, such as thromboxanes and leukotriens, add insult to injury. While skin damage accumulates with age, repair processes slow down. Thus, any boost by a molecule that would reduce free radicals and accelerate molecular events in healing has the potential to hasten skin repair. Tb4 has such healing qualities.
Our research mainly focusses on this early social experiences that people have that can be positive or negative, and that can really shape our developing brain. There have been some very interesting studies, for example, with children that grew up in Romanian orphanages. And we know that that early start, where it's really deprived from social contact and physical contact, had a massive impact. So we see that oxytocin levels, for example, are much lower than we would expect in other kids.
Potential side effects of 5-HTP include heartburn, stomach pain, nausea, vomiting, diarrhea, drowsiness, sexual problems, vivid dreams or nightmares, and muscle problems.[19] Because 5-HTP has not been thoroughly studied in a clinical setting, possible side effects and interactions with other drugs are not well known. According to the US National Institute of Health TOXNET, 5-HTP has not been associated with serotonin syndrome or any serious adverse events in humans.[20] Across multiple studies, 5-HTP also been reported to not cause any noticeable hematological or cardiovascular changes.[21] 5-HTP also has not been associated with eosinophilia.[22]
