PT-141 (Bremelanotide) is a melanocortin receptor agonist investigated for its effects on sexual desire and arousal:

• Brain-First Mechanism: Activates melanocortin receptors (MC3R/MC4R) involved in sexual function not dependent on peripheral vasodilation (distinct from PDE5 inhibitors).

• For Men & Women: Studied for low libido/HSDD, with reports of heightened arousal, improved satisfaction, and stronger intimate connection.

• ED Contexts: Investigated as an option even in some non-responders to PDE5 inhibitors, via neural rather than purely vascular pathways.

• Experience Enhancers: Users in research settings often note increased sensitivity, natural lubrication, and perceived intensity.

• General Note: As with all research compounds, responses vary by protocol design, dose, timing, and baseline status.
