Melanostatine MELST

An older, obscure hormone studied for blocking the release of a skin-pigment-related hormone, mostly in older physiology research rather than as a marketed product. Human data are sparse and come from older studies rather than modern trials.

Also known as Nonapeptide-1, Melanostatine 5, White 05, Nonapeptide-1 [INCI], 64W45420K5, Met-pro-phe-arg-trp-phe-lys-pro-val, RefChem:202301, Nonapeptide 1
