For Research Use OnlyPT-141 – 10mg
PT-141 is a cyclic melanocortin-receptor peptide drawn from the same structural lineage as Melanotan II but engaging the family more narrowly. Supplied lyophilised, 10mg per vial at $4.50 per mg. Narrower engagement means an observed result carries fewer candidate explanations, which suits a subtype-specific question and disadvantages one framed at the level of the family as a whole. As with any cyclic peptide the manufacturing step most likely to be left incomplete is ring closure, and the open-chain precursor sits too close in mass to separate by spectrometry alone, so ask for the chromatographic trace rather than the headline purity figure.
