Cortagen
Also known as: AEDP, Ala-Glu-Asp-Pro
Cortagen is a synthetic tetrapeptide (Ala-Glu-Asp-Pro, AEDP) short-peptide bioregulator derived from amino-acid analysis of Cortexin, a polypeptide preparation from cow brain cortex. It was developed by Vladimir Khavinson and colleagues at the St. Petersburg Institute of Bioregulation and Gerontology and is reported to act on cortical neurons by entering the nucleus and influencing tissue-specific gene expression. The research group claims neuroprotective and nerve-repair effects; evidence is limited to single-group preclinical and small clinical work, and it is not FDA-approved.

Prices observed from public storefronts (last 24h), normalized to $/mg. "Evidence" is Merit's 0–100 Merit Score, derived only from observable verification evidence (methodology on /about); "Purity" is the latest independent COA. Some buy links are affiliate links — Merit may earn a commission at no extra cost to you, and where a vendor offers one, the code shown gets you a discount at their checkout. Affiliate status never affects price data, ranking, or the Merit Score (full policy on /disclosure). Research use only.
