Computed with the same four public criteria as every profile. The human-evidence grade on an indexed profile is set automatically and may change when it is hand-reviewed. It is not a safety score, not a purity rating, and not medical advice, and not a claim that this compound treats, cures, or prevents any condition.
What it is
Semax + Selank is a combination of two synthetic peptides developed in Russia. Semax is an analog of a fragment of ACTH and is thought to influence brain-derived neurotrophic factor and related signaling, while Selank is an analog of the immune peptide tuftsin and is thought to affect GABA-related and monoamine systems. The blend is marketed for cognitive and anxiety-related effects.
What the evidence shows
Neither peptide is FDA-approved, and the combination itself has no clearly identified registered human trials or published studies. Some small human studies exist for each peptide individually, mostly from Russian research groups, but evidence for the blend specifically is unclear and appears to rest largely on community reports.
What is in this blend
A blend is scored on its own, but the evidence for each ingredient lives on its own profile. Mixing compounds adds unknowns that none of the individual studies cover.
