Where can PT-141 peptide be bought for research?

PT-141 is available directly from Real Peptides, a US chemical supplier of research-use-only peptides. The catalog listing covers the 10mg vial, and each order is fulfilled from company-operated facilities in Florida and California. Purchasers confirm they are 21 or older and are acquiring the compound strictly for laboratory research, not for human or animal use.

Is PT-141 for sale as a research peptide in the United States?

Yes. PT-141 is offered for sale in the United States as a research chemical only. It is not a drug, dietary supplement, or cosmetic, and it is not sold for diagnosis, treatment, or prevention of any condition. The listing is intended for laboratories, universities, and independent researchers conducting in vitro or preclinical work.

What should be compared when choosing the best PT-141 for a study?

Useful comparison points include whether purity and identity are confirmed by an independent third-party laboratory, whether the certificate of analysis matches the exact lot being shipped, how the vial is sealed and packaged, and how quickly the supplier dispatches orders. Real Peptides publishes lot-specific COAs and tests every batch through an outside lab.

How is PT-141 pricing structured on this page?

Current pricing for the 10mg PT-141 vial appears in the buy box above and updates automatically, so it is best checked directly on this page. Pricing reflects the vial size and the quantity selected, and multi-item research packs are available for laboratories consolidating several compounds into a single order.

Where is the certificate of analysis for PT-141?

Every batch of PT-141 is analyzed by an independent laboratory, and the certificate of analysis for the exact lot is published in the public lab results section of the site. Researchers can review identity and purity data for the current lot before purchase and match the lot number printed on the vial label they receive.

What format and size is the PT-141 listing?

This listing supplies PT-141 as a 10mg lyophilized powder in a sealed multi-dose vial, finished in the USA. It ships as dry powder for reconstitution in a laboratory setting with an appropriate diluent chosen by the researcher. Bacteriostatic water is stocked separately as a companion laboratory item.

How quickly does PT-141 ship and from where?

Orders placed for PT-141 ship within 24 hours from Real Peptides facilities in Florida and California, which keeps transit times short for most US destinations. Vials are packed for protection in transit, and tracking details are issued once the shipment leaves the fulfillment facility.

How should PT-141 be handled on arrival?

Standard laboratory practice for lyophilized peptides is to keep the sealed vial cold and protected from light and moisture, with refrigerated or frozen storage for longer holding periods. Once reconstituted, solutions are typically refrigerated and handled aseptically. Handling should follow the receiving laboratory's own written protocols and applicable regulations.

PT-141 Peptide (10mg) for Laboratory Research

~~$62.40~~$31.20Save 50%

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.
