| Summary | Melanotan II is a synthetic cyclic analog of alpha-melanocyte-stimulating hormone that activates several melanocortin receptors, studied in small early human trials for skin pigmentation and erectile function. It has never been approved as a medicine, and its further development moved to related compounds such as bremelanotide (PT-141). Current literature on its safety consists mainly of case reports from unregulated use. |
