Selank vs Semax
Both are Russian-developed peptides registered as medicines in Russia but unapproved in the US and UK. Selank is positioned around anxiety, Semax around cognition and stroke recovery — with evidence bases that largely predate Western-standard trials.
Selank and Semax are usually researched together as the 'Russian nootropic' pair. The practical reality is the same for both: real regulatory approval exists in Russia, but neither is an approved medicine in the US or UK, so products sold in those markets are grey-market. This comparison explains the difference in their intended uses and the shared limits of their evidence.
