SEE-max
A synthetic brain peptide derived from ACTH that enhances focus, memory, and neuroprotection — developed in Russia.
Last reviewed: April 2026
Semax is a synthetic fragment of ACTH (adrenocorticotropic hormone) with modifications for brain specificity. It enhances BDNF production, improves attention and memory, and provides neuroprotection — without the cortisol-raising effects of natural ACTH.
