Overview
PT-141 — Melanocortin-receptor agonist
What is PT-141?
PT-141 (bremelanotide) is a cyclic peptide agonist of the melanocortin receptors, developed as a derivative of Melanotan II. Where most melanocortin research tools act peripherally, PT-141 is studied for its activity at central melanocortin pathways — the MC3/MC4 receptor axis that sits at the centre of appetite, arousal, and energy-balance signalling research.
Why researchers choose it
The melanocortin system is one of neuroscience's busiest intersections, and PT-141 is among its best-characterised probes, with a development history reaching through clinical study. Its cyclic structure gives it the stability linear analogs lack. REPRIME supplies a lyophilized 10 mg vial for laboratory work.
The REPRIME standard
A well-travelled molecule still gets the full evidence chain. Every batch is independently HPLC-tested and released at ≥99% main-peak purity, with the batch COA published in the Certificates repository. The 10 mg lyophilized vial ships cold-chain in tamper-evident packaging with a unique REP-XXXX-XXXX-X code — one scan at first use confirms it is genuine. For laboratory and research use only; not for human consumption.
Storage
Store lyophilized at -20°C. After reconstitution, refrigerate at 2-8°C.
Research use only
For laboratory and research use only. Not for human or animal consumption.
