  • PT-141 is a peptide synthetically derived from alpha-melanocyte-stimulating hormone which is vital in protecting the skin from UV rays, developing skin pigmentation, controlling appetite, and supporting sexual functions.

Research on PT-141 has primarily focused on its effects on sexual function. Studies have found that PT-141 works by activating melanocortin receptors in the brain, which can lead to increased sexual excitement, and improved sexual desire and arousal.

Some studies have also suggested that PT-141 may have potential therapeutic uses beyond sexual function, such as in inflammatory bowel disease management and as a potential anti-cancer agent.
