Description

PT-141 (Bremelanotide) Research Peptide

 

PT-141 research peptide, also known as bremelanotide, is a synthetic cyclic peptide associated with the melanocortin receptor system. It is a seven-amino-acid peptide with a defined structure that makes it suitable for laboratory investigations involving peptide-receptor interactions, molecular characterization and structure-function research.

PT-141 Research Peptide was originally investigated under the code name PT-141 and is now also known by the generic name bremelanotide. Public chemical databases identify bremelanotide as an oligopeptide and melanocortin receptor agonist.

For research purposes, PT-141 can be used as a defined peptide model for controlled biochemical and analytical experiments.

PT-141 Chemical Information

PubChem lists the free-base form of bremelanotide with molecular formula C₅₀H₆₈N₁₄O₁₀ and molecular weight 1025.2 g/mol.

PT-141 Acetate

If the LV product is specifically supplied as bremelanotide acetate, the chemical information is different from the free-base form. PubChem lists bremelanotide acetate as C₅₀H₇₀N₁₄O₁₁ with a molecular weight of approximately 1043.2 g/mol.

Important: The LV product page should identify the actual chemical form being supplied and use the corresponding batch documentation. Do not label an acetate product as the free base, or vice versa.

Research Use Disclaimer

FOR RESEARCH USE ONLY

PT-141 supplied by LV Longevity Peptides is intended solely for qualified laboratory and research applications.

Not for human consumption, human administration, veterinary use, diagnosis, treatment or prevention of disease.

PT-141/bremelanotide also has an approved pharmaceutical drug context in the United States. FDA labeling identifies Vyleesi (bremelanotide injection) as a prescription product for a specific indication in premenopausal women and states that it is not indicated to enhance sexual performance.

That pharmaceutical status should not be used to imply that a research-material product is approved for human administration.
