PT-141 10mg (CAS 189691-06-3) – Libido-Enhancing Peptide API

PT-141 10mg (CAS 189691-06-3) is a high-purity libido-enhancing peptide API, featuring ≥98% purity (HPLC-verified) and a cyclic heptapeptide structure (molecular weight: ~1025 Da). As an α-MSH analog, it non-selectively activates melanocortin receptors (MC1R/MC4R) to promote neurotransmitter release (dopamine, oxytocin), thereby enhancing libido and improving sexual function.

This lyophilized peptide exhibits excellent water solubility and stable activity under -20℃ storage. It is widely used in preclinical research on sexual dysfunction: it aids in studying male erectile dysfunction and female hypoactive sexual desire disorder (HSDD), with FDA approval background for HSDD treatment. Unlike traditional ED drugs, it avoids vascular dilation side effects, making it a valuable tool for exploring melanocortin-related sexual function regulation mechanisms. For pharmaceutical R&D teams, its reliable activity and clear mechanism provide a solid foundation for sexual health research.
