Semax is a synthetic peptide derived from ACTH(4-10), originally developed in Russia and studied extensively for its neuroprotective and nootropic properties. Research indicates Semax may increase BDNF levels and influence dopaminergic and serotonergic systems, making it of significant interest in neuroscience research.
