Melanotan 2 — 10mg

Melanotan II is a synthetic cyclic heptapeptide analog of alpha-melanocyte-stimulating hormone (α-MSH). It acts primarily on melanocortin receptors (MC1R through MC5R) and has been widely studied for its effects on melanogenesis — the biological pathway governing pigmentation. Research has also examined its activity related to appetite modulation, lipid metabolism, and sexual function pathways. Melanotan II remains one of the most referenced compounds in melanocortin receptor research due to its broad receptor affinity and diverse biological activity profile.
