Cortagen

Animal & lab onlyBrain, mood & sleep

A 4-amino-acid Khavinson “bioregulator” (Ala-Glu-Asp-Pro) modeled on brain-cortex extracts, sold for brain and nerve support.

Not approved for human use; sold as a research chemical.

Used for

  • Brain recovery and cognition
  • Nerve repair

How it works

Claimed, like other bioregulators, to adjust gene activity in its target tissue. In rats it acted as an antioxidant and eased signs of reduced blood flow to the brain.

What the research shows

  • Russian rat studies: less oxidative damage and better brain metabolism in chronic reduced blood flow, studied alongside Cortexin (a brain-extract drug).
  • No controlled human trials.

Dosing

Dosing isn’t listed on the public site. In the app, each published option is shown with its source (a drug label, a clinical guideline, a trial or community reports) and can be turned into a protocol you review.

Side effects

  • Few reported

Cautions

  • Research-chemical vials have no quality control: purity, dose and sterility vary. Third-party testing helps but is no guarantee.

Storage

Unmixed powder: freezer or fridge, away from light.

Once mixed with bacteriostatic water: fridge; the common rule is to use it within 28 days.

There is no label or published stability data for this one, so treat these as habits, not limits.
