Science-backed research overview for this compound
Melanotan II (MT-2) is a cyclic heptapeptide analogue of the natural alpha-melanocyte stimulating hormone. It is a more potent and stable version of Melanotan I, designed for enhanced receptor binding and a longer half-life.
MT-2 works by non-selectively binding to several melanocortin receptors (MC1, MC3, MC4, and MC5). While MC1R activation induces skin tanning, its interaction with MC4R in the brain leads to appetite suppression and significant increases in libido and sexual function.
Research into MT-2 is extensive, covering its effects on weight loss, erectile dysfunction, and photoprotection. It is a unique compound in the research world due to its ability to simultaneously affect pigmentation, metabolism, and behavior through the melanocortin system.
