Information Sheet

What It Is

PT-141 (bremelanotide) is a melanocortin-receptor agonist peptide that drives sexual desire centrally (via the brain) rather than through blood flow; used for low libido and ED.

Mechanism & Notes

  • Activates MC3R/MC4R melanocortin receptors in the brain's reward/desire circuits
  • Onset ~45–60 min, clears within hours; may also modulate appetite/metabolism
