Melanotan II 10mg Research Peptide

Melanotan II is a cyclic lactam heptapeptide and synthetic analogue of alpha-melanocyte stimulating hormone (α-MSH). It binds non-selectively to melanocortin receptors MC1R, MC3R, MC4R, and MC5R, making it a versatile research tool for studying the melanocortin system. Research has focused extensively on pigmentation biology via MC1R activation, sexual function pathways mediated through MC4R, and appetite regulation through central melanocortin signalling. Melanotan II demonstrates greater potency than linear MSH analogues due to its cyclic structure, which confers enhanced metabolic stability and receptor binding affinity. The compound’s interaction with MC4R has generated particular research interest in sexual behaviour and erectile function pathways, while its MC1R activity has been studied in melanogenesis and UV-protective pigmentation research. As a non-selective melanocortin receptor agonist, Melanotan II provides researchers with a broad pharmacological tool for investigating the diverse physiological roles of the melanocortin system, including energy homeostasis, inflammatory responses, and cardiovascular function.
