Semax Research
Semax is a synthetic heptapeptide derived from ACTH (adrenocorticotropic hormone), developed in Russia for cognitive enhancement and neurological conditions. Unlike ACTH, Semax has no hormonal activity and doesn't affect cortisol levels. Research has shown it increases BDNF (brain-derived neurotrophic factor), NGF (nerve growth factor), and enhances dopaminergic and serotonergic transmission. It's approved in Russia for stroke recovery, cognitive disorders, and optic nerve diseases. Users report improved focus, memory, mental clarity, and verbal fluency. Studies suggest neuroprotective properties and potential benefits for ADHD and depression.
