Know your compound
Semax is a short synthetic peptide based on a fragment of the hormone ACTH. It was developed in Russia and is used there in stroke and cognition research.
What grabs researchers is its effect on BDNF — brain-derived neurotrophic factor, a protein that helps brain cells grow, repair, and form new connections. In rat studies Semax raised BDNF in the brain and switched on genes tied to neural repair after a stroke-like injury.

The research
The published findings behind this compound — the headline numbers, in plain terms, each cited to source. Preclinical results are directional (animal / in-vitro) and shown for context, not as therapeutic claims.
In rat studies, Semax bound in the basal forebrain and raised levels of BDNF — a protein that helps brain cells grow and repair — above untreated controls.
Rat basal forebrain; directional finding, magnitudes illustrative.
After a stroke-like injury in rats, Semax switched on genes for neurotrophins and their receptors — the growth-factor machinery tied to neural repair.
Rat cerebral ischemia; transcription upregulated vs control.
In rodents, Semax activated the brain's dopamine and serotonin systems — the signaling pathways behind mood, motivation and focus.
Rodent brain; directional finding, magnitudes illustrative.
Semax has been studied in people at different stages of ischemic stroke, tracing its path from lab findings toward clinical evaluation.
