PT-141 (Bremelanotide) is a melanocortin receptor agonist that works through the central nervous system to enhance sexual desire and arousal — rather than acting on the vascular system like traditional treatments. This neurological mechanism makes it effective for both men and women experiencing reduced libido or sexual dysfunction. It promotes spontaneous desire and responsiveness, supporting a more natural and fulfilling sexual experience. Prescribed and monitored by a licensed provider as part of a personalized sexual health protocol.
