Melanotan II is a cyclic lactam analogue of alpha-melanocyte stimulating hormone with broad melanocortin receptor activity. Research has examined its binding profile across MC1R, MC3R, MC4R, and MC5R subtypes, with studies focusing on pigmentation signaling, energy homeostasis pathways, and sexual function research models.

Its cyclic structure confers greater receptor binding potency compared to linear analogues in research settings, making it a widely studied tool compound in melanocortin receptor pharmacology.

Each vial is supplied as lyophilized powder, third-party tested via LC-MS analysis, and ships with a Certificate of Analysis.
