Khavinson cerebral-cortex bioregulator
Cortagen is a Khavinson tetrapeptide bioregulator (Ala-Glu-Asp-Pro / AEDP) originally isolated from cerebral-cortex extracts in Russian gerontology research. It has been studied in animal and cell-culture models for neuroprotection, neuronal differentiation, and cognitive ageing, alongside the related pineal peptides Pinealon and Epitalon. Sold by research-peptide vendors at 5–20 mg vial sizes for laboratory work; not approved by FDA, MHRA, Health Canada, or TGA for human use.
