Semax
Neuroprotective cognitive enhancer
Semax is a synthetic heptapeptide analogue of ACTH (4-10) originally developed in Russia for neurological conditions. It is studied for its neuroprotective effects, cognitive enhancement, and ability to increase brain-derived neurotrophic factor (BDNF) — a key protein in learning and memory.
Research Benefits
How It Works
Semax increases the expression of BDNF and its receptor TrkB, promoting neuroplasticity and neuronal survival. It also modulates serotonergic and dopaminergic neurotransmission, enhancing mood, focus, and cognitive processing speed.
