PT-141 — also written PT 141 or PT141, and known pharmaceutically as bremelanotide (CAS 189691-06-3, molecular formula C50H68N14O10) — is a synthetic cyclic heptapeptide and melanocortin receptor agonist studied for its interaction with melanocortin receptor pathways, particularly the MC4R and MC3R receptors. PhaseOne has PT-141 for sale online to researchers across Australia as a high-purity lyophilised powder, independently HPLC verified at ≥99% purity per batch.
As a melanocortin analogue structurally related to Melanotan II, PT 141 is studied within Australian peptide research for melanocortin receptor signalling, manufactured to research-grade standards and independently third-party tested for identity and consistency, with every order shipped Australia-wide.

PT-141 — also known as bremelanotide — is a synthetic cyclic heptapeptide and melanocortin receptor agonist, studied within Australian peptide research for its interaction with melanocortin receptors, particularly MC4R and MC3R.
PT 141 peptide is the same compound as PT-141 — the hyphen is often dropped, and it also appears written PT141. All refer to bremelanotide, the melanocortin receptor agonist PhaseOne supplies in 10mg vials for laboratory research use only.
Yes. Bremelanotide is the pharmaceutical name for the compound also known as PT-141, PT 141 or PT141. The two names describe the same cyclic heptapeptide. PhaseOne supplies it as a research-grade lyophilised powder.
Vyleesi is the brand name under which bremelanotide is supplied as a prescription medicine in some markets. The active peptide is the same, but the branded medicine and PhaseOne's research-grade lyophilised powder are different products supplied through entirely different channels.
PT-141 is a metabolite of Melanotan II. Both act at melanocortin receptors, but PT-141 lacks the MC1R-associated activity that characterises Melanotan II research, which is why the two are studied separately. PhaseOne supplies both. (!) View our Melanotan II.
PhaseOne ships PT-141 Australia-wide for research use, dispatched locally with tracking, in 10mg vials. Every vial carries a batch-specific Certificate of Analysis verifying ≥99% HPLC purity.
Yes — PhaseOne has PT 141 peptide for sale online in 10mg vials, shipped Australia-wide. Online results for bremelanotide mix research-grade lyophilised powder with branded prescription products supplied through clinical channels. PhaseOne supplies the former, with a batch Certificate of Analysis on every vial.
PhaseOne prices PT-141 at A$61.99 for a 10mg vial, with the batch Certificate of Analysis included at no extra cost. Current pricing is shown on this page.
No. Chemist Warehouse and other Australian chemists do not stock research-grade PT-141. Where bremelanotide is supplied as a prescription medicine it is dispensed under the Vyleesi brand through clinical channels, which is a different product from the research-grade lyophilised powder PhaseOne supplies.
Yes - PhaseOne provides a peptide dosage calculator researchers can use as a reference tool when planning reconstitution and dilution. Use our peptide dosage calculator.
PT-141 is a melanocortin analogue structurally related to Melanotan II; both are studied for melanocortin receptor pathways, but they have distinct structures and research profiles. (!) View our Melanotan II.
Unreconstituted PT-141 should be stored refrigerated and protected from light, and is commonly reconstituted with bacteriostatic water prior to research preparation. (!) Read our reconstitution guide.
Each PhaseOne batch is independently verified by third-party HPLC analysis, with a Certificate of Analysis available for every order shipped across Australia.
PT-141 is studied within the melanocortin peptide research category, alongside related melanocortin analogues. (!) Explore more in our peptide guides.
