Selank (5 mg) + Semax (5mg)

This combination brings together Selank, Semax. Explore each component’s research focus below, followed by the evidence for the combination.

Research focus & potential applications

Selank

Selank is explored for GABA-related signaling and stress-response mechanisms. Preclinical gene-expression findings help explain the research interest, without establishing relief of anxiety or better focus in humans.

Semax

Semax is investigated for neurotrophic signaling, including BDNF and TrkB. These pathways are relevant to neuronal adaptation; the cited preclinical findings do not establish better human memory or concentration.

Selank

Read the findings & sources

Preclinical evidence

A rat study found changes in expression of genes associated with GABA signaling after Selank exposure. GABA is involved in inhibitory communication between neurons, which explains interest in stress-related mechanisms. Changes in gene expression do not themselves demonstrate relief of anxiety or improved attention in humans, and they do not predict a blend's effects.

Semax

Read the findings & sources

Preclinical evidence

A rat hippocampus study reported changes in BDNF and TrkB signaling and performance in a conditioned behavioral task after Semax. BDNF is involved in neuronal adaptation. These observations are a basis for mechanistic research; they do not establish a reliable improvement in human memory, attention or recovery after stroke.
