Melanotan II

Melanotan II is a cyclic peptide analog of alpha-MSH that interacts with multiple melanocortin receptors, including MC3R and MC4R. It is studied in research exploring pigmentation, sexual-behavior pathways, and appetite regulation, and is used in laboratory settings to investigate melanocortin system dynamics. Shipped in freeze-dried (lyophilized) form; requires reconstitution.
