PT-141
A melanocortin-receptor agonist that acts on pathways in the central nervous system.
What this compound is.
PT-141, also called bremelanotide, is a melanocortin-receptor agonist. Unlike agents that act on blood flow, it acts on melanocortin pathways in the central nervous system — a different mechanism, and the reason it is studied separately from vascular approaches.
It has been examined in clinical research relating to sexual-health concerns in adults, which is the context in which it is most often discussed.
How it has been studied.
Neutral notes on how this compound has been studied. These are not claims of safety or effectiveness, and not medical advice.
Studied clinically in the context of sexual-health and libido concerns in adults.
Examined for its central (nervous-system) mechanism rather than a vascular one.
Reviewed within melanocortin-pathway research more broadly.
Format, and what a provider weighs.
Prescribed formulations are typically administered by subcutaneous injection. Form and suitability are a provider's decision — nothing here is a recommendation, a protocol, or a dose.
- A provider reviews cardiovascular history and blood pressure, current medications, and other factors before considering a prescription.
- Not appropriate during pregnancy or while breastfeeding.
- Whether it is appropriate for you is a clinical decision, and availability varies by state.
PT-141 cannot be purchased directly on this site. It is available only after a licensed provider evaluates your intake and determines that treatment is clinically appropriate, and it is dispensed by a licensed compounding pharmacy. Eligibility is never guaranteed, and availability varies by state. See how it works and our approach to care.
