Melanocortin receptor agonist for pigmentation and receptor-binding research. Supplied as lyophilized powder — bacteriostatic water required for reconstitution.
Melanotan II (MT2) is a synthetic cyclic peptide analog of alpha-melanocyte-stimulating hormone (α-MSH). It binds melanocortin receptors (MC1R–MC5R) and is used in pigmentation, photoprotection, and receptor pharmacology research.
