Melanotan II (MT-2) functions by stimulating the alpha-MSH receptor. This is a receptor that produces melanin, which aids in the darkening of skin pigmentation. Because of this action, the individual will tan easier and darker than he would without the use of MT-2.

There are several alpha-MSH receptors in the body. Melanotan II functions by stimulating the MC1-5 receptor. Stimulation of this receptor promotes darkening of the skin. MT-2 also stimulates the MC4 receptor, which acts to increase penile erectile function.

Clinical trials have shown promising results for Melanotan II in regards to erectile dysfunction. However, despite clinical trials the peptide has never been approved by the U.S. government for human use:

2000 - UAZ College of Medicine (Urology) - Findings: Promoted erections in 17 of 20 subjects, tip rigidity increased by 80%. 68% experienced increase in libido.

1998 - UAZ College of Medicine (Pharmacology) - Findings: Promoted erections in 80% of men, tip rigidity increased by 80%.
Note - all erectile dysfunction studies are based on psychogenic erectile dysfunction, which refers to erectile dysfunction of a physiological nature not a physical one. However, many anecdotal reports state stronger erections and better performance when used as a sex aid despite no existing erectile dysfunction.
Effects   
The effects of Melanotan two revolve around nothing more than tanning and possible erectile dysfunction relief. A darker and deeper tan may be noticed in a few days (assuming one is also tanning) and should produce notable results in a few weeks. The longer one uses MT-2 the darker he will get.
The effects of Melanotan II on erectile dysfunction take approximately 4-6 hours to take effect and should last 6-12 hours depending on individual response. Timing is important if used for this purpose. However, there are those that run small daily to every other day doses in order to provide a maintenance relief, but this can prove problematic to the skin if not careful.
D osage
Start with a dose of 1mg daily for the first two or three days and, if level of side effects permit, look

to increase dosage by 0.25mg every day over the next several days until you reach a daily dosage

of 2-3mg. This level should be adequate for most users, though some may wish to increase yet further,

perhaps as high as 5mg daily in order to achieve a very deep tan. A maintenance phase as described

above is then used.
