From the FDA Global Substance Registration System, the registry that assigns every substance the FDA tracks a unique identifier.

How to read this. This page reports what federal records say about Bremelanotide, nothing more. An FDA approval covers specific uses and doses on a reviewed label. A registered trial records that research was declared, not that it succeeded. A listed patent governs who may sell a drug, not whether it works. None of this is medical advice, and none of it means a compound is safe to use outside a prescription.
