Description

PT-141 is a synthetic cyclic heptapeptide and melanocortin receptor agonist, derived from Melanotan II through removal of the C-terminal amide group. Unlike its precursor, PT-141 does not produce significant skin pigmentation effects. Research has focused on its role in melanocortin receptor activation, particularly MC3R and MC4R pathways, and its effects on central nervous system signalling. It is supplied in lyophilised form for research purposes.
