PT-141

PT‑141 (Bremelanotide) is a synthetic peptide analogue of alpha-melanocyte-stimulating hormone (α‑MSH) commonly used in laboratory research to study melanocortin receptor activity and sexual behaviour pathways. It is of interest in controlled experimental settings investigating receptor signalling, neuroendocrine mechanisms, and peptide–receptor interactions. PT‑141 is supplied strictly for research purposes only and is not intended for human or veterinary use.
