Melanotan II (MT-2) is a synthetic alpha-MSH analogue activating melanocortin receptors to produce: increased melanin (skin darkening), appetite suppression, enhanced libido and sexual function, and potential fat loss. The tanning effect persists for weeks after stopping. MT-2 is the parent compound from which PT-141 was derived. Side effects include nausea (especially early), facial flushing, spontaneous erections in men, and mole darkening — dermatologist monitoring of moles is recommended.
