What is Semax?
Semax is a synthetic peptide derived from a fragment of ACTH, developed in Russia and researched for cognitive enhancement and neuroprotection, including in the context of stroke recovery in regional clinical studies.
Also known as: ACTH 4-10 analog
How Semax is studied
Semax is a synthetic peptide derived from a fragment of ACTH, developed in Russia and studied for cognitive and neuroprotective effects. Research points to influence on BDNF and other neurotrophic factors, and it has been used in regional clinical settings including stroke recovery.

Semax — frequently asked questions
Memory and focus, neuroprotection, and — in regional clinical studies — stroke recovery. Evidence is largely region-specific.
No. It is not an approved medication in the US or EU. Much of the clinical use and research is based in Russia.
They are often discussed together as Russian-developed neuropeptides, but Semax leans cognitive/neuroprotective while Selank leans anxiolytic.
