Cortagen

Cortagen is a synthetic tetrapeptide (Ala-Glu-Asp-Pro) from the Khavinson bioregulator family, designed to act on cerebral cortex tissue. It is studied for neurological function, cognitive performance, and neuronal repair in Russian research. It is sold strictly for laboratory use.

Cortagen is the cortex-specific peptide in Khavinson's bioregulator catalog. The premise is that short peptides can encode tissue-specific instructions — Cortagen for the cerebral cortex, Pinealon for the pineal gland, Cardiogen for the heart. Researchers study Cortagen for memory, attention, and recovery after brain injury or age-related cognitive decline.

As a short bioregulator peptide, Cortagen is hypothesized to penetrate cells and modulate transcription of cortex-specific genes. Animal and cell-culture studies report improved cognitive performance markers, increased neuronal survival under stress, and modulation of inflammation in cortical tissue. Mechanistic precision lags behind larger, better-characterized neuropeptides.

Cortagen sits in the longevity-forum bioregulator niche along with Pinealon and Epitalon. Most discussion is informal, citing Russian research, with users describing cognitive and stress-resilience benefits anecdotally. Far less mainstream than Semax or Cerebrolysin.

“A tiny tissue switch for the cortex.”

Cortagen is commonly stacked with Pinealon (also brain-targeted) and Epitalon in longevity bioregulator protocols. Some users combine it with Semax for daytime cognitive effects.
