What this means
- 01
FDA has approved PT-141 for at least one labeled indication, so a pharmaceutical-grade product exists in the United States and is dispensed on prescription.
- 02
Approval is indication-specific. Uses outside the label are a clinical decision for a prescriber, not something the approval itself authorizes.
- 03
Unlicensed online vials, including those labeled "research use only", are not the approved product and are not covered by the approval.
What PT-141 is
An FDA-approved melanocortin agonist for hypoactive sexual desire disorder in premenopausal women.
PT-141, or bremelanotide, is a melanocortin receptor agonist approved by the FDA as Vyleesi for acquired, generalized hypoactive sexual desire disorder in premenopausal women. Unlike vascular treatments, it acts centrally on pathways involved in sexual desire.
Mechanism: Agonizes central melanocortin receptors (notably MC4R) involved in sexual arousal and desire pathways.
Regulatory history: FDA-approved (Vyleesi)
How FDA treats this kind of product
Approves prescription drugs by indication and polices unapproved products, including peptides sold online. Compounding pharmacies may prepare some compounds under a prescription when the FDA places them on a permitted bulk-substances category.
The classification above is the The Longevity Archive reading of U.S. Food and Drug Administration listings for PT-141 at the reviewed date, not a legal opinion. Rules change, and importing, prescribing and possessing a compound can each be treated differently. Check the regulator directly before acting on anything here.
