Aliases: Ala-Glu-Asp-Pro · AEDP
Last verified: 2026-09-23
The short version
A brain-series tetrapeptide — neuroprotection and nerve-tissue regeneration; potential in TBI and neurodegeneration. Key fact: Human data are limited: small trials or case-series reports exist, without large randomized studies. Preclinical studies. Status: research chemical. Not approved in the West.
Identity & type
- Molecular type
- bioregulator
- Origin
- A brain-series tetrapeptide — neuroprotection and nerve-tissue regeneration; potential in TBI and neurodegeneration.
Mechanism of action
Regulation of neuronal-differentiation gene expression; reduced oxidative stress.
not confirmed in humans
Dosing & routes
Official / clinical context
No approved official document exists for Cortagen. Any protocols mentioned are to be read as information, not as a recommendation.
Regulator-approved labeling and published study designs — never a recommendation.
Community-reported practice
1–5 mg/day SC in courses. A brain bioregulator: users describe a mild calming/clarity effect; often combined with Pinealon.
Unverified self-reports. Not medical advice. Not endorsement.
Expected effects (community)
A brain bioregulator: users describe a mild calming/clarity effect; often combined with Pinealon.
Protocol — official vs community
Official / label
No approved protocol exists. Cortagen is a research peptide bioregulator (Ala-Glu-Asp-Pro) with no registered drug product in any major market.
Duration: —
Preclinical neuroprotection data from the originating group; no registered human trial.
Community (anecdotal)
1–5 mg SC daily for 10–20 days.
- Cycle:
- 1–2 courses per year.
- Break:
- Months between courses.
The regimen is the shared Khavinson course pattern; only the brain/neuroregeneration targeting claim differs from the rest of the series.
Human evidence
