Melanocortin research peptide
Bremelanotide (PT-141) is a synthetic cyclic heptapeptide — a seven-amino-acid chain closed by an intramolecular lactam bridge and structurally derived from the α-melanocyte-stimulating hormone (α-MSH) fragment, functioning as an agonist at melanocortin receptors (notably MC3R and MC4R). In published preclinical literature it has been investigated for its interaction with melanocortin-receptor signaling pathways in the central nervous system. Supplied lyophilized at ≥99% HPLC purity with a per-lot Certificate of Analysis. For laboratory and research use only — not for human or animal consumption. ROEHN makes no claims regarding its effects.
