Much like melanotan I (afamelanotide), melanotan II stimulates the production of eumelanin, causing the skin to go darker (tanning). Melanotan II is usually administered as an injection of liquid underneath the skin, commonly every second day. Trials have shown that the tanning effect can occur within 5 doses.
BY INJECTION UNDER THE SKIN:
For causing an erection in men with ED: the typical dosage of melanotan-II is 0.025 mg/kg.
For tanning skin: the typical dosage of melanotan-II is 0.025 mg/kg.
