A melanocortin stack pairing Melanotan II for tanning with PT-141 for libido — same receptor family, two effects.
Melanotan II is a melanocortin agonist used for skin tanning (via melanogenesis), and as a side effect it also raises libido — because it hits the same melanocortin pathways as PT-141. This stack pairs them for people chasing both effects.
Caveats are significant: Melanotan II is unlicensed, causes nausea and darkening of moles, and the long-term safety data is poor — the compound page doesn't soft-pedal this. Listed for educational completeness, not endorsement.
