PT-141 10MG

PT-141 (Ac-Nle-cyclo[Asp-His-D-Phe-Arg-Trp-Lys]-OH) is a cyclic, lactam-bridged analog of α-melanocyte-stimulating hormone (α-MSH) originally developed as a tanning peptide. It acts centrally via activation of the melanocortin-4 receptor (MC4R) in the hypothalamus. As noted in the peer-reviewed literature, bremelanotide is a melanocortin receptor agonist of interest for the study of central melanocortin signaling pathways (sciencedirect.com). This research-grade lyophilized powder is synthesized under strict quality controls and provided with full analytical documentation. For Research Use Only. Not for human use.
