PT-141, also known as bremelanotide, is a melanocortin receptor agonist peptide (mainly MC3R and MC4R). Derived from research on α-MSH analogs, it is studied in the context of sexual function through central nervous system pathways. NeoPeptidos offers it as research-grade material, ≥99% HPLC purity.

What is PT-141?
Unlike the analogs focused on pigmentation, PT-141 acts prominently on melanocortin receptors in the central nervous system. Because of that profile it is studied in pathways different from those of the Melanotans, within research on behavior and physiology.
Research context
The literature on PT-141 / bremelanotide has focused on central melanocortin pathways related to sexual function in models and clinical studies.
The NeoPeptidos product is research-grade material; it includes no indications or administration schedules and is intended exclusively for researchers.
