Semax
Semax is a synthetic peptide, an analog of a fragment of adrenocorticotropic hormone(ACTH), developed in Russia for its nootropic (cognitive-enhancing), acting by crossing the blood-brain barrier to boostBDNF,memory,learning, and protect neurons without hormonal effects. It’s used in Russia for stroke,Parkinson’s, and other neurological issues, working intranasally, and research shows it helps with attention, stress, and neurodegenerative conditions by affecting brain.

About this compound
Semax is a synthetic heptapeptide (Met-Glu-His-Phe-Pro-Gly-Pro) derived from the ACTH(4-7) fragment, with a Pro-Gly-Pro C-terminal extension conferring increased resistance to enzymatic degradation. It does not bind to ACTH receptors (MC2R), making it useful for studying ACTH-derived peptide signaling independent of cortisol axis effects.
