Melanotan II is a synthetic cyclic heptapeptide analog of alpha-melanocyte-stimulating hormone (α-MSH). It acts on melanocortin receptors (primarily MC1R and MC4R) to stimulate melanogenesis — the production of melanin pigment in the skin. Research has demonstrated its efficacy in increasing skin pigmentation (tanning) even without UV exposure, as well as effects on libido and appetite suppression via central nervous system melanocortin pathways. Melanotan II is one of the highest-demand peptides in the wholesale market, particularly in regions with strong tanning culture. Supplied as pharmaceutical-grade lyophilized powder.
