Semax

Semax is a synthetic peptide analogue derived from the adrenocorticotropic hormone fragment ACTH(4-10), modified to improve stability and neuroactive duration. It has been studied extensively in cognitive research for its relationship to neurotrophic signaling, memory pathways, stress-response modulation, and central nervous system plasticity across experimental and clinical settings.

Semax is a synthetic peptide analogue derived from the adrenocorticotropic hormone fragment ACTH(4-10), modified to improve stability and neuroactive duration. It has been studied extensively in cognitive research for its relationship to neurotrophic signaling, memory pathways, stress-response modulation, and central nervous system plasticity across experimental and clinical settings. Its Pro-Gly-Pro extension differentiates it structurally from the native ACTH fragment and substantially alters peptide stability characteristics. Lyophilized powder, 3mL vial. Sold at 10mg per vial. For research use only.

Heptapeptide Met-Glu-His-Phe-Pro-Gly-Pro. ACTH(4-7) analog with Pro-Gly-Pro extension.
