Quick Facts
Mechanism of Action
PT-141, also known as bremelanotide, is a melanocortin-receptor agonist peptide. Its mechanism acts centrally through melanocortin pathways connected to sexual-arousal signaling.
Mechanism of Action: acts centrally through melanocortin pathways connected to sexual-arousal signaling.
- Supports sexual-desire pathways through melanocortin receptor activity [1].
- Clinical literature documents use of bremelanotide/PT-141 in hypoactive sexual desire disorder research [1].
- Acts centrally rather than through vascular-only mechanisms, making it distinct from PDE5-style approaches [1].
- Official medical databases include trial and drug-information records for this pathway [2][5].

Supplies Needed — Estimate
Select a vial strength and an example reconstitution volume below. Counts use only the checked, computable rows above; they are not product-specific sterility, compatibility, or stability guidance.
Select a compatible vial and volume below to view quantities.
Educational and entertainment purposes only. Research use only; not for human or animal administration. Pad counts assume two per Total entry; syringe counts include additional containers where a single entry exceeds the selected syringe capacity. Vial totals assume full theoretical recovery and do not account for dead volume, spoilage, asepsis, expiration, potency, route, or beyond-use dating. These figures are not a recommended supplies list for an actual procedure.
