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.
Real 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.

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).
Rigorous Quality Testing
Each batch of PT-141 undergoes multiple layers of analytical verification to ensure consistent lab performance. Peptide purity is confirmed at ≥99% via high-performance liquid chromatography (HPLC), while peptide sequence integrity is validated through tandem mass spectrometry (MS/MS). Endotoxin levels are certified below 0.1 EU/mg to prevent assay interference, and thermal stability is assessed by Fourier-transform infrared spectroscopy (FT-IR) and differential scanning calorimetry (DSC). These quality controls guarantee that every vial delivers reliable, research-grade peptide for sensitive protocol applications.
Why Choose PT-141?
PT-141 stands out in peptide research for its high selectivity toward melanocortin-4 receptors, enabling precise investigation of neuromodulatory pathways without cross-reactivity in erythropoietic or metabolic receptor systems. Its well-documented use in rodent and non-human primate models provides a robust evidence base for experimental design. Each PT-141 lot is accompanied by a Certificate of Analysis (COA), offering full traceability from synthesis through batch release. under cGMP-like conditions, PT-141 ensures consistency and compliance for all your laboratory needs.
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.
