Semax is a synthetic peptide derived from the adrenocorticotropic hormone (ACTH) fragment 4-10. Developed at the Institute of Molecular Genetics of the Russian Academy of Sciences, it has been used in Russia since the 1990s for various neurological conditions, including stroke recovery and cognitive impairment.

How It Works

The peptide's primary mechanism involves increasing brain-derived neurotrophic factor (BDNF) levels, which supports neuronal health, synaptic plasticity, and cognitive function. Semax also modulates the serotoninergic and dopaminergic systems, contributing to mood stabilization and focus enhancement.

Unlike stimulant-based cognitive enhancers, Semax provides cognitive benefits without the typical side effects of increased heart rate, anxiety, or dependency. Its neuroprotective properties have made it popular among biohackers seeking sustainable cognitive optimization.
