Semax is a heptapeptide derived from a fragment of adrenocorticotropic hormone (ACTH). It has a long history in Russian research and clinical use, and is studied for BDNF (brain-derived neurotrophic factor) signaling and cognition.
Research investigates it for focus, mental clarity, and neuroprotective pathways in models. Western clinical data is more limited than the Eastern research base.
