What is Melanotan II

Melanotan II is a synthetic cyclic heptapeptide analog of α-MSH, a naturally occurring peptide that regulates pigmentation through target receptor activation. Originally developed as a research compound for studying melanogenesis and photoprotective pathways, MT-II exhibits high affinity for its primary target receptor subtypes. Through selective binding to multiple pathway targets, it has been examined in research contexts involving pigmentation pathways, endocrine signaling, and peptide-receptor pharmacology in laboratory settings.
