Clinical Evidence

What the literature says

Scientific Overview

Cortagen is one of the Khavinson short peptides (Ala-Glu-Asp-Pro), claimed to be a 'cerebrocortex-tropic' peptide bioregulator. Russian publications report cognitive and neuroprotective effects after stroke; Western peer-reviewed replication is sparse. Treat efficacy claims with caution outside the original publishing group.
