PT-141 (bremelanotide) is a melanocortin-receptor agonist derived from Melanotan II, studied for centrally mediated sexual-function signaling in research.

PT-141 (Bremelanotide)

  • Cyclic melanocortin-receptor agonist derived from Melanotan II

    Acts mainly on the MC4R / MC3R receptors

  • Studied for centrally mediated sexual-function signaling

    Acts through the nervous system rather than the vasculature

  • Referenced in libido and arousal research models

Research Use Notes

  • Supplied as lyophilized powder

    Requires reconstitution before use

  • Research Water required for mixing (sold separately)

    Swirl gently, never shake

Storage

  • Store lyophilized vial frozen for long-term holding

  • Keep reconstituted solution at 2 to 8°C

    Protect from light and heat

Handling

  • Maintain sterile technique throughout reconstitution

    For laboratory research use only

  • Avoid repeated freeze-thaw cycles to preserve integrity
