Technical notes
Material Profile
PT-141 is a metabolite-derived analog of Melanotan II: a seven-residue lactam-cyclized peptide (1025.18 Da) with an N-terminal acetyl group, cyclized between the Asp side chain and the Lys side chain.
Unlike peripherally acting agents, PT-141 is studied for centrally mediated melanocortin signaling; research endpoints in the literature include MC4R receptor affinity, hypothalamic signaling pathway mapping, and sexual-response neurocircuitry models in preclinical systems.
Net peptide content, purity, and fill weight are stated on the certificate so molar concentrations can be calculated precisely for receptor-binding and cell-culture work.
Compliance
PT-141 is supplied strictly as a laboratory reference material. It is not a drug, supplement, food, or cosmetic, and it is not for therapeutic or diagnostic use, human consumption, or veterinary use. Purchasers are responsible for handling the material in accordance with their institutional and jurisdictional requirements.
