Dated milestones in GHK-Cu’s U.S. regulatory path.

1. Late 2023

   Placed on FDA Category 2 (do-not-compound list), restricting compounding-pharmacy access.

2. April 23, 2026

   Removed from FDA Category 2 compounding list. Removal is NOT the same as Category 1 status or FDA approval.

3. July 23–24, 2026

   Pharmacy Compounding Advisory Committee (PCAC) voted to recommend inclusion on the 503A Bulks List. Advisory only — as of September 2026 the FDA had not completed rulemaking, so compounding is not yet permitted on this basis.
