PT-141(Bremelanotide) 10mg (Coming Soon)
PT-141, also called bremelanotide, is a synthetic cyclic heptapeptide analogue of alpha-melanocyte-stimulating hormone and a known metabolite of Melanotan II, described in the literature as a melanocortin receptor agonist with activity at MC4R. It is stocked as a reference compound for in vitro and preclinical neuroendocrine, receptor-binding, and vascular signaling research.
RegenX Peptides supplies PT-141 as a 10mg lyophilized powder in a sealed multi-dose vial for reconstitution under laboratory conditions. Identity and purity are verified by an independent analytical laboratory, and the certificate of analysis for the current lot is published on the lab results page so it can be reviewed before purchase. Orders ship from facilities in Florida and California within 24 hours. Sold for research use only, not for human or veterinary use.
Finished in the USA
PT-141 (Bremelanotide) is a lab-grade melanocortin-4 receptor agonist peptide designed for advanced neuromodulation and vascular signaling research. Widely cited in male sexual behavior and penile blood-flow studies, PT-141 offers precise MC4R activation without off-target erythropoietic effects. Each vial is verified to ≥99% purity, and supplied with a full Certificate of Analysis (COA).
What Sets PT-141 Apart
Unlike broader-acting melanocortin peptides, PT-141 delivers targeted activation of central melanocortin-4 receptors, making it uniquely suited for research into sexual arousal circuitry and vascular function. Its molecular design avoids off-target effects on red blood cell production and systemic metabolism, allowing clear interpretation of neuromodulatory and endothelial endpoints. Coupled with its demonstrated stability in both lyophilized and reconstituted forms, PT-141 offers researchers unparalleled confidence in long-term study reproducibility and data integrity.
