The FDA's Center for Veterinary Medicine accepted the reasonable-expectation-of-effectiveness section in February 2025 and the target-animal-safety section in January 2026, both firsts for a longevity drug.

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 LOY-002 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.
