Research overview

PT-141 is a synthetic cyclic peptide from the melanocortin family, also catalogued under the name Bremelanotide. It carries the molecular formula C50H68N14O10 and the CAS number 189691-06-3, and structurally it is a cyclic analog of the melanocortin peptide alpha-MSH. Kits Peptides stocks it in a single 10mg presentation. Within the literature, PT-141 shows up mainly in melanocortin-system research, the field concerned with the melanocortin receptor subtypes (MC1R through MC5R) and how peptide ligands interact with them. Groups working in peptide pharmacology and receptor-binding studies reference it as a cyclic melanocortin-receptor peptide. We supply it purely as a reference material for laboratory research use only, with no human or veterinary application. Each vial ships as lyophilized reference material and comes with an independent third-party certificate of analysis matched to its lot, so the identity and purity on paper correspond to the exact vial in hand. Orders leave our Vancouver facility with tracking and reach research customers across Canada. Anyone looking to buy PT-141 in Canada will find this listing third-party tested and dispatched domestically.

PT-141 (Bremelanotide) is a cyclic melanocortin peptide referenced in melanocortin-receptor and peptide-pharmacology research. It is supplied as a lyophilized reference standard for laboratory research use only, lot-numbered, with the certificate published for any lot that has been independently analysed.
