What Is Melanotan 2?

Melanotan II is a synthetic cyclic peptide analogue of alpha-melanocyte-stimulating hormone (α-MSH). It was developed at the University of Arizona during melanogenesis research. MT2 is a non-selective melanocortin receptor agonist: it binds MC1R, which drives pigmentation, as well as MC3R and MC4R, which are linked to appetite and sexual-function signalling. That broad receptor profile is why it remains a common reference compound in melanocortin research.

MT2 research also led to PT-141 (bremelanotide), a metabolite of MT2 studied for MC4R-mediated effects.

Is MT2 the same as Melanotan II?

Yes. MT2, MT-II and Melanotan 2 are all names for the same peptide.
