This bundle combines Semax and Selank, two peptides from the same Russian research group, approved there as nasal-spray prescription products for cognitive support (Semax) and anxiolytic use (Selank) respectively. Neither is FDA-approved.
Why are Semax and Selank bundled together?+
Both come from the same research lineage and are frequently discussed together for complementary cognitive and mood-related research.
Are Semax and Selank FDA-approved?+
No. Both have regulatory approval in Russia as prescription products but are not approved by the FDA or EMA.
Can I read about each compound individually?+
Yes, Semax and Selank each have their own dedicated page on this site with a full research overview and FAQ.
Why do these two specifically get combined?+
Because their mechanisms don't overlap. Semax activates and sharpens focus through BDNF and dopamine pathways; Selank calms and steadies through GABA and serotonin. Complementary rather than redundant, which is why it's one of the most common nootropic peptide pairings.
