Common questions
Yes. PT-141 is the research designation for bremelanotide. See the PT-141 research guide.
PT-141 is a metabolite of MT-2 (Melanotan II). They share a cyclic structure; PT-141 ends in a free acid where MT-2 ends in an amide, and PT-141 research centers on the MC4 receptor rather than pigmentation.

Lyophilized powder keeps at −20 °C for long-term storage or 2–8 °C short-term. Once reconstituted with bacteriostatic water, refrigerate at 2–8 °C and keep it out of light. Our reconstitution guide covers the full process.
PT-141 (Bremelanotide) 10 mg, Melanocortin Research Peptide
PT-141, also known as Bremelanotide, is a synthetic cyclic 7–amino acid peptide and an agonist of the melanocortin receptors. It is a frequent subject of preclinical and laboratory investigation into melanocortin-pathway signaling. Lumen Research supplies PT-141 as a high-purity lyophilized powder intended exclusively for in-vitro research and laboratory study.
About PT-141
PT-141 is a cyclic analog within the melanocortin family studied as a research tool for melanocortin-receptor biology. Published research is indexed in the peer-reviewed scientific literature.
PT-141 Research Applications
In laboratory and preclinical settings, this peptide is studied across several areas of interest:
Melanocortin-receptor signaling: examined across MC1R–MC5R subtypes in research models.
MC4R pathway research: investigated for central-signaling activity.
Neuropeptide-signaling studies: studied in receptor-interaction research.
Pigmentation research: explored via melanocortin-pathway models.
These describe areas of ongoing scientific investigation only, this compound is not a therapeutic product and no clinical outcomes are implied.
Supplied as a lyophilized powder, the peptide is typically reconstituted with bacteriostatic or sterile water for laboratory use. Store the sealed lyophilized vial at -20 °C, protected from light and moisture, for long-term stability. After reconstitution, store at 2–8 °C and use within the timeframe defined by your laboratory protocol. Handle using standard laboratory safety practices.
