Why is semax not FDA approved?
It has not gone through the FDA's drug approval process at all. That process needs the maker to run the specific studies the FDA reviews. Semax is approved in Russia and Ukraine based on research done there, but that approval does not carry over to the US. A US advisory panel did vote in July 2026 to recommend it for use by compounding pharmacies, but the FDA has not finalized any rule based on that vote.
