Why is semax described as banned?
This site's legal fields do not say banned. They say not approved, research use only in the US, not licensed in the UK, and not approved in Australia or Canada. Semax is approved in Russia and Ukraine for stroke and thinking problems. Unapproved is not the same as banned. In July 2026 the US Pharmacy Compounding Advisory Committee voted to recommend it for compounding, against the advice of FDA scientists. That vote is advice only. It is not a ban or an approval. This FAQ reports those national fields and that difference, not a slogan from a store listing.

Part of names, absences, and legal limits. Brand versus molecule, side effects this site's citations did not measure, how long the trials actually ran, what national legal-status fields can say, and why two-compound answers do not scale to a larger stack.
