Overview
Semax is a synthetic peptide based on a fragment of ACTH, developed in Russia and studied for cognitive enhancement, focus, and neuroprotection, including after stroke in Russian clinical settings.
How It's Thought to Work
Research suggests Semax may raise BDNF and modulate dopamine and serotonin systems, supporting attention and neuroprotection.
What the Research Says
Clinical research is largely Russian; it is approved and used there for certain neurological indications, but has minimal Western regulatory review.
Regulatory & Legal Status
Not FDA-approved. Sold as a research chemical in most Western markets.
Safety Considerations
Limited Western safety data; unregulated purity. Consult a qualified clinician.
