What Is PT-141?

PT-141, also known as Bremelanotide, is a synthetic melanocortin peptide derived from Melanotan II. Unlike Melanotan II, PT-141 does not produce significant tanning effects. Its primary research interest lies in its activity at melanocortin receptors (MC1R, MC3R, MC4R), particularly those involved in central nervous system signalling pathways relating to arousal, motivation, and autonomic function.

PT-141 has been extensively studied in models of sexual dysfunction and CNS arousal, and has received FDA approval (as Vyleesi) in the US for hypoactive sexual desire disorder, making it a well-characterised compound with a substantial research base.
