§ About PT-141

PT-141, also known as bremelanotide, is a cyclic melanocortin peptide studied for agonist activity at melanocortin receptors including MC3R and MC4R. Its development emerged from research involving melanocortin analogues, including work related to Melanotan II, with subsequent investigation focusing on central melanocortin receptor signalling.

PepDirect supplies PT-141 strictly as laboratory research material. This product is not supplied or marketed as an approved medicinal product.

§ PT-141 and Melanotan II

PT-141 emerged from melanocortin-analogue research related to Melanotan II but is a distinct compound with its own chemical identity and receptor profile. Research findings for one should not be represented as findings for the other, and the two compounds are not interchangeable in the research literature.

§ FAQ

What is PT-141?: PT-141 is a cyclic melanocortin peptide studied for agonist activity at melanocortin receptors including MC3R and MC4R. Research literature investigates its receptor pharmacology and central melanocortin signalling pathways.
What is another name for PT-141?: PT-141 is also known as bremelanotide. The two names refer to the same cyclic melanocortin peptide identity.
What receptors does PT-141 interact with?: Published research examines PT-141 activity at melanocortin receptors, with particular attention to MC3R and MC4R. The wider melanocortin receptor family is also relevant context for comparative studies.
Is PT-141 the same as Melanotan II?: No. PT-141 emerged from melanocortin-analogue research related to Melanotan II but is a distinct compound with its own chemical identity and receptor profile.
Is this PepDirect product an approved medicine?: No. PepDirect supplies this PT-141 material strictly as a laboratory research product. It is not supplied or marketed as an approved medicinal product.
How is PepDirect PT-141 tested?: PT-141 is tested by HPLC to a purity of ≥ 99.5%. The current lot displayed on this page is TM-2488. A lot-specific Certificate of Analysis is published on the product page before purchase and ships in the box.
Is this intended for human use?: No. All PepDirect products are sold strictly for laboratory and research use only, and are not intended for human or veterinary use, consumption, or any clinical or diagnostic application.
