PT-141 — 10 mg

PT-141 (Bremelanotide) is a synthetic peptide derived from the melanocortin pathway. It is studied for its effects on sexual function, libido enhancement, and central nervous system modulation of arousal, acting directly on melanocortin receptors in the brain.

Benefits

• Libido enhancement — studied for increasing sexual desire in both men and women.
• Central action — works directly on the brain’s melanocortin system, unlike PDE5 inhibitors.
• Versatility — explored for arousal issues independent of vascular function.
• Research in both sexes — investigated for female sexual dysfunction as well as erectile function in men.
• Fast-acting — studied for acute improvements in sexual readiness.

What researchers look at

• Mechanism: melanocortin receptor (MC3/MC4R) agonism in the hypothalamus.
• Clinical trials for female sexual interest/arousal disorder (FSIAD).
• Studies in erectile dysfunction models independent of nitric oxide pathways.
• Exploration of central vs. peripheral arousal mechanisms.
