Semax (also known as ACTH 4-10 analog) is a neuropeptide studied for cognition and neuroprotection. This page covers what the published research does — and does not — establish about it in relation to focus, memory and cognition.
Semax is researched for Memory & focus, Neuroprotection — which is why it appears in discussions of focus, memory and cognition.
Research status: Primarily Russian clinical and preclinical research.
How Semax is thought to work
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.
What it does not establish
Evidence is largely region-specific. Not an approved medication in the US/EU.
Nothing on this page is a recommendation to use Semax, and Selpho publishes no dosing, reconstitution or sourcing information. Read how we decide what goes in the library.
