Structure of the compound on this page.
PT-141 (Bremelanotide) from Cleared Peptides is a research-grade compound supplied for laboratory and analytical investigation. Every lot is third-party tested, and the batch Certificate of Analysis is published before sale. Specifications, CAS number and molecular formula are listed below.
Research use only. PT-141 (Bremelanotide) is supplied for laboratory research. It is not a drug, food, cosmetic, or dietary supplement. It is not FDA-approved. It is not for human or veterinary administration. This page does not give a dose or a method of administration. A study cited on this page describes that study’s own test article. It does not make this lot an approved medicine. To check a fact, open the PubMed or DOI link, confirm the authors and year, and match the paper’s compound name, CAS number, or sequence to the specification table. The full method is on the research desk page. Identity and purity for a lot are only what that lot’s certificate of analysis reports. An HPLC percentage is not a sterility result and not an endotoxin result unless the certificate prints those tests.
