Description
Semax is a synthetic heptapeptide derived from the adrenocorticotropic hormone (ACTH) fragment ACTH(4–10). It is widely studied for its nootropic, neuroprotective, and cognitive-enhancing properties. Research suggests Semax may support memory formation, focus, mental clarity, and resistance to stress by modulating neurotransmitter activity and promoting neurotrophic factor expression.
Semax has also been investigated for its potential role in neuroprotection, cognitive recovery, and mood regulation without exhibiting significant stimulant or sedative effects. It is commonly utilized in laboratory studies exploring cognitive performance, neural plasticity, and brain health.
This compound is intended strictly for laboratory research and clinical investigation purposes only.
