Melanotan-2

Melanotan-2 is a cyclic synthetic melanocortin analogue derived from alpha-melanocyte-stimulating hormone and engineered for greater receptor affinity and biological stability. It has been studied extensively in aesthetic and neuroendocrine research for its relationship to melanogenesis, pigmentation signaling, appetite pathways, and melanocortin receptor activity across experimental models.

What is Melanotan-2?

Aesthetic · 10mg · 3mL

Melanotan-2 is a cyclic synthetic melanocortin analogue derived from alpha-melanocyte-stimulating hormone and engineered for greater receptor affinity and biological stability. It has been studied extensively in aesthetic and neuroendocrine research for its relationship to melanogenesis, pigmentation signaling, appetite pathways, and melanocortin receptor activity across experimental models. Its cyclic lactam structure substantially improves peptide stability relative to earlier linear melanocortin analogues. Lyophilized powder, 3mL vial. Sold at 10mg per vial. For research use only.

Cyclic heptapeptide. Ac-Nle-cyclo(Asp-His-D-Phe-Arg-Trp-Lys)-NH₂. More compact than MT-1.
