Melanotan II has been used to serve the purpose of tanning in humans. The clinical trials of this product indicate that the side effects that subjects experienced after they used the product for two weeks on a daily basis were mild fatigue, mild nausea and spontaneous erections since the subjects were all males. In the clinical trials, the dose that the subjects took was three to four times higher than the recommended dose.
The positive effects of using Melanotan according to the clinical trials are that subjects experienced increased tanning on their faces and bodies. Even if they did not expose their skin to UV rays, a person looking at them could easily notice that their skin was tanned. Melanotan can be acquired from a number of online suppliers like Europatan, in the form of an injection or nasal spray variety.
The clinical studies on Melanotan II were therefore discontinued since it is not feasible to treat a patient with a product to alleviate a certain skin condition and at the same time deal with an additional side effect such as erections. For this reason, Melanotan I was the product that researchers targeted for regulatory approval in the treatment of rare skin conditions that would benefit from increased use of melanin. Further in the clinical trials, researchers used PT-141, which is also known as Bremelanotide and which is an analog of Melanotan II, to remove the part that was responsible for tanning. They selected it for the attempted regulatory approval for treating sexual dysfunction.
However, since Melanotan II is able to increase melanin in the skin and to also increase sexual arousal, instead of just one of these effects, it cannot be marketed to only a single group of people. For this reason, you will find that this product is marketed to people who want to achieve cosmetic tanning. Users of the product who are male simply need to ignore the side effect of experiencing spontaneous erections after they inject themselves with it. They can also choose to take a lower dose of Melatonin II.
