It shares the same cyclic backbone as PT-141, differing only by its C-terminal amide, which accounts for the small differences in formula and molecular weight. In preclinical research, MC1R activation on melanocytes drives melanogenesis, while central MC3R/MC4R activation is implicated in studies of appetite/energy balance and arousal-related pathways. Reported research interest centers on melanocortin pharmacology, melanogenesis/photoprotection (as a tool compound), food-intake regulation, and neuroprotective effects observed in vivo. Research applications Melanocortin receptor (MC1R/MC3R/MC4R) research Preclinical melanogenesis / pigmentation-biology models Central melanocortin regulation of energy balance Quality & documentation Every lot is tested by an independent third-party laboratory before it enters the catalog.
