Named peptide stack · Nootropic Peptides
Cognitive Stack
The Cognitive Stack pairs two Russian-research nootropic peptides developed at the Institute of Molecular Genetics in Moscow: Semax (ACTH 4-10 heptapeptide) and Selank (tuftsin-derived heptapeptide). Both are licensed Russian Federation pharmaceuticals for specific neurological indications. UK status: research-tier only.
Why researchers pair these compounds
Semax is registered in Russia for acute ischaemic stroke. Selank is registered in Russia for generalised anxiety disorder. Combined use in the Russian clinical-research literature reports broader cognitive and anxiolytic effects than either alone.
Both compounds are administered as nasal sprays in the Russian clinical context. Some UK retailers stock injectable variants.
Western validation of the Russian research is sparse. Treat as preliminary preclinical evidence, not established clinical fact.
Mechanism
Semax modulates BDNF and NGF expression in rodent brain tissue. Selank modulates enkephalin-degrading enzyme activity and GABA-system signalling. Combined effects in Russian clinical literature.
Components
Selank
Tuftsin-derived heptapeptide. Russian-registered for generalised anxiety disorder.

Frequently asked questions
Are Semax and Selank legal in the UK?
They are not UK-licensed medicines. UK research peptide retailers sell them under research-use-only framing.
Why nasal spray?
Russian clinical-trial administration uses nasal-spray formulation. This is the route documented in the published Russian trial work.
PeptideClear does not sell, dispense, prescribe, or recommend Cognitive Stack for any specific person. This page is editorial commentary on the published preclinical literature and the UK retail landscape. Every research peptide on this page is sold under research-use-only framing.
