Cortagen
Khavinson tetrapeptide (Ala-Glu-Asp-Pro) marketed for cortical/CNS support.
Cognitive effects may be perceived acutely to within days; sustained benefit depends on continued use.
Store the lyophilized powder refrigerated (2 to 8 C), or frozen for long-term storage, protected from light. After reconstitution with bacteriostatic water, keep refrigerated and use within about 4 weeks.
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.
