PT-141

PT-141, also known as Bremelanotide, is a synthetic peptide originally derived from the melanocortin peptide hormone family. It was developed from modifications of Melanotan II, but unlike its parent compound, PT-141 is highly selective for the melanocortin-4 receptor (MC4R) and melanocortin-1 receptor (MC1R). These receptors are implicated in regulating sexual arousal, energy homeostasis, and certain aspects of mood and behavior.

Unlike other compounds often explored in this category, PT-141 does not act through the vascular system (such as nitric oxide pathways). Instead, it influences the central nervous system directly, making it a unique subject of study in sexual health and neurological function.

Note: PT-141 is intended for research purposes only and is not approved for human consumption. All products are shipped in lyophilized form and must be reconstituted to a liquid for research and testing. We are unable to provide any dosing instructions.
