What brands say it does
Melanotan II activates melanocortin receptors, increasing skin pigmentation and (as a side effect) libido. It is not FDA-approved; injectable products sold online are unregulated with risks of nausea, mole changes, and unknown purity. Scenesse (afamelanotide) is a related approved implant for a rare light-sensitivity disorder.
Where you’ll find it
Unregulated online vendors—avoid. Legitimate medicine uses different approved melanocortin drugs.
