Semax

Semax (Met-Glu-His-Phe-Pro-Gly-Pro) is a synthetic nootropic peptide originally developed in Russia. It was designed to retain the neuroprotective and cognitive-enhancing properties of ACTH while eliminating the hormonal effects associated with cortisol stimulation. Research suggests that Semax may increase Brain-Derived Neurotrophic Factor (BDNF) and Nerve Growth Factor (NGF), two proteins involved in neuronal growth, repair, and synaptic plasticity.

Semax has been investigated for its potential to support memory retention, concentration, learning capacity, mental performance, mood balance, and recovery following neurological stress. Unlike traditional stimulants, it does not appear to act by forcing neurotransmitter release, but rather by supporting long-term neural adaptation and brain health.

In Russia, Semax has been used clinically for conditions including stroke recovery, cognitive impairment, and certain optic nerve disorders, although it is not approved as a medication in many other countries. Current interest in Semax largely comes from research and nootropic communities exploring its effects on neuroplasticity, focus, and cognitive performance.
