PT-141 Overview
PT-141, also known as Bremelanotide, is a synthetic peptide analog of α-melanocyte-stimulating hormone (α-MSH). It is studied in laboratory and preclinical models for its ability to activate melanocortin receptors (MC3R and MC4R), which are involved in neuroendocrine signaling, energy regulation, and vascular pathways.
Dorr R.T. et al. (1996).
History
PT-141 was developed through research into melanocortin-class peptides, originally derived from modifications of Melanotan II. While Melanotan II was primarily studied for its pigmentation pathway properties, PT-141 was synthesized to focus on central target receptor activity. Since its discovery, PT-141 has been investigated in models of neuroendocrine function, vascular signaling, and peptide-receptor dynamics.

Each vial contains the labelled quantity of lyophilized peptide. The stated milligram figure refers to the peptide content, not the total mass of the lyophilized cake.
Reconstitution requires bacteriostatic water and appropriate laboratory equipment, which are not included.
Products ship as research materials without directions for use. Handling should follow your own laboratory protocols.
Store lyophilized material at 2-8°C and away from light. Once reconstituted, follow your laboratory's stability guidance.
