PT-141

PT-141 (Bremelanotide) – Research Peptide

PT-141 (also known as Bremelanotide) is a synthetic research peptide derived from α-Melanocyte Stimulating Hormone (α-MSH). It is widely referenced in in-vitro research models examining melanocortin receptor activity—particularly MC3R and MC4R—and their role in cellular signaling, neurotransmission, and metabolic regulation.

Manufactured to rigorous laboratory standards, each batch of PT-141 is verified through High-Performance Liquid Chromatography (HPLC) to confirm a purity of ≥99%. This reagent is supplied for use in biochemical, neurophysiological, and receptor-targeted peptide research.
