Melanotan II: An Important Distinction This distinction is critical for understanding PT-141's (lack of) skin effects: Melanotan II Non-selective melanocortin receptor agonist activating MC1R, MC3R, MC4R, and MC5R Strong MC1R activation stimulates melanocytes (pigment-producing cells in the skin) to produce melanin Produces significant skin darkening/tanning Not FDA-approved and carries significant safety concerns PT-141 (Bremelanotide) More selective for MC4R, with reduced activity at MC1R compared to Melanotan II Designed to activate central nervous system receptors for sexual function Minimal tanning effect at therapeutic doses FDA-approved with established safety data In short, the compound that affects skin (Melanotan II) isn't PT-141, and the compound that's FDA-approved (PT-141) has minimal skin effects
