What is PT-141 (Bremelanotide)?
PT-141, also called bremelanotide, is a synthetic peptide of seven amino acids arranged in a ring. It was made from Melanotan II, itself a version of the natural hormone alpha-MSH, by changing one chemical group at the end of the ring. It acts at melanocortin receptors, a family of receptors found in the brain and elsewhere in the body. Research on it falls into two areas: how it acts on those receptors in animals, and a completed program of human clinical trials in premenopausal women.

PT-141 (Bremelanotide) Research & Reference
What PT-141 (Bremelanotide) does in published studies, and how to work with it in the laboratory, are covered in full on two dedicated pages rather than summarised here, so neither the evidence nor the handling detail is cut short.
Certificates of Analysis
Every batch is tested by an independent laboratory before release. The certificate covering this batch of PT-141 (Bremelanotide), and its safety data sheet, are below as PDFs, so the figures on this page can be checked against the source.
Frequently Asked Questions
Is PT-141 (Bremelanotide) independently tested for purity?+−
Yes. Every batch of PT-141 (Bremelanotide) is tested by an independent third-party laboratory using HPLC and MS-UPLC, confirming purity and mass identity before the batch is released. Pure Peptides does not test its own material.
Can I see the Certificate of Analysis before buying?+−
Yes. The Certificate of Analysis for the batch currently in stock can be viewed and downloaded directly on this page, before you place an order. Each certificate states the batch number, the measured purity, and the date of analysis, and can be verified independently with the issuing laboratory using the report number it carries.
What does "Research Use Only" mean?+−
It means PT-141 (Bremelanotide) is supplied for in-vitro laboratory research and for no other purpose, and must not be administered to humans or animals. PT-141's regulatory status differs from most compounds in this catalog: bremelanotide is the active ingredient of a prescription medicine sold under another name. The material sold by Pure Peptides is a research-grade preparation, supplied strictly for in vitro and non-clinical laboratory research; it is not that medicine and holds no marketing authorisation.
How is PT-141 (Bremelanotide) shipped and stored?+−
PT-141 (Bremelanotide) ships from US stock with cold-chain packaging and full tracking; orders placed before noon EST on business days are typically dispatched the same business day. On arrival, store the lyophilized powder at -20°C or below, dry and protected from light.
