Russian-developed ACTH analog that upregulates BDNF, enhances dopaminergic and serotonergic tone, and improves memory, focus, and neuroprotection.
Overview
Semax is a heptapeptide analog of ACTH(4-10) developed at the Institute of Molecular Genetics in Moscow and approved in Russia for stroke, cognitive decline, and optic nerve disease. It dramatically upregulates BDNF (brain-derived neurotrophic factor) and its receptor TrkB, enhancing synaptic plasticity and neuronal survival. It also modulates dopaminergic, serotonergic, and cholinergic systems for acute cognitive enhancement.
