For research use only. Not for human consumption.
Overview
PT-141 (Bremelanotide) is a synthetic cyclic heptapeptide and melanocortin receptor agonist with high affinity for MC3R and MC4R receptor subtypes. Unlike phosphodiesterase inhibitors, PT-141 acts on central melanocortin pathways in the hypothalamus, modulating neural circuits involved in arousal and sexual response. It is derived from the α-MSH analog Melanotan-II via metabolic processing and is studied for its unique mechanism of action on central nervous system pathways.

Frequently Asked Questions
PT-141 (Bremelanotide) is a synthetic cyclic heptapeptide and melanocortin receptor agonist with high affinity for MC3R and MC4R receptor subtypes. It acts on central melanocortin pathways in the hypothalamus and is derived from the alpha-MSH analog Melanotan-II.
Unlike MT-2 which activates multiple melanocortin receptor subtypes (MC1R through MC5R), PT-141 has greater selectivity for MC3R and MC4R. This selectivity profile makes it a preferred research tool for studying central nervous system melanocortin signaling pathways without broad peripheral effects.
PT-141 is verified at ≥99% purity via HPLC. Store lyophilized powder at -20°C. After reconstitution, refrigerate at 2–8°C and use within 30 days. COA included with every order.
Yes. PT-141 ships as a lyophilized powder requiring reconstitution with bacteriostatic water before use in research protocols.
