Full shipping details

PT-141 (bremelanotide) is a synthetic heptapeptide melanocortin receptor agonist that has been extensively studied for its interactions with the central nervous system melanocortin pathways. This peptide represents a novel approach to researching sexual function and arousal mechanisms through melanocortin receptor activation rather than traditional vascular pathways. Research contexts include investigations into melanocortin-4 receptor (MC4R) signalling, central arousal mechanisms, and the complex neurochemistry of sexual behaviour. PT-141 has also been studied for its potential effects on mood regulation and social bonding mechanisms in animal models. AllMyPeptides supplies PT-141 as a lyophilised research peptide with rigorous independent HPLC testing by independent third-party laboratories. Every batch is verified to 99%+ purity with a comprehensive Certificate of Analysis.

Frequently Asked Questions

What is the purity of your PT-141?+
Our PT-141 is 99%+ pure, verified by independent third-party HPLC and mass spectrometry analysis. A Certificate of Analysis (COA) is included with every order.
How should I store PT-141?+
PT-141 should be stored in a cool, dry place away from direct light. For long-term storage, refrigeration at 2-8°C is recommended. Always reconstitute with bacteriostatic water and use proper aseptic technique.
How do I reconstitute PT-141?+
Use our free Peptide Calculator to determine the correct amount of bacteriostatic water for your desired concentration. Slowly inject the water down the side of the vial — do not spray directly onto the peptide. Gently swirl until fully dissolved.
Is PT-141 for human consumption?+
No. All products sold by AllMyPeptides are strictly for in vitro research and laboratory use only. They are not intended for human consumption, diagnostic, or therapeutic purposes. Purchasers must be qualified researchers aged 18 or over.
