Description
PT-141, also catalogued as Bremelanotide, is available to buy at PeptaMED in a convenient dosing pen with full analytical traceability. The product is intended exclusively for research applications.
What is PT-141?
PT-141 is a cyclic heptapeptide of the melanocortin family, originally identified as an active metabolite of Melanotan II. What sets it apart in the eyes of researchers is its mechanism: it acts primarily through the melanocortin receptors MC4R and MC3R — central nervous system signalling pathways rather than vascular ones.
This centrally mediated, receptor-driven mechanism distinguishes PT-141 from other compounds under study and has made it a frequent tool in preclinical investigations of melanocortin signalling. The extensive literature surrounding the molecule considerably simplifies the planning and validation of new receptor experiments.
Format and Quality
PT-141 ships as a stabilised solution in a pre-filled dosing pen with 200 graduations of 50 mcg — 10 mg in total. Batches are tested by an independent laboratory using HPLC, with documented purity of ≥99% and a certificate of analysis available. Store refrigerated, away from direct light. The packaging is designed for laboratory use, with batch labelling and graduations that support reproducible measurement.
