How Semax + Selank works, and what the research shows.
Combines Russia's two best-known therapeutic neuropeptides: Semax (an ACTH-fragment nootropic that upregulates BDNF, supporting focus and cognitive resilience) with Selank (a tuftsin-analog anxiolytic that calms GABAergic signaling without sedation) — targeting sharper cognition and lower anxiety simultaneously.
Both peptides are approved medicines in Russia — Semax for stroke and cognitive indications, Selank for anxiety — each supported by Russian clinical trials.
That evidence has not been replicated in Western randomized controlled trials, so the combination is prescribed off-label in the US as an investigational cognitive protocol.
