Cortagen — Vendor Pricing & Purity Guide
Research Overview
Cortagen is a synthetic tetrapeptide bioregulator (Ala-Glu-Asp-Pro) developed by Dr. Khavinson targeting cerebral cortex tissue. It modulates gene expression in cortical neurons and has been studied for cognitive enhancement and neuroprotection in aging and post-stroke recovery.
In Russian clinical studies, Cortagen improved cognitive function, attention, and memory in elderly patients and in individuals recovering from cerebrovascular events.
Key Research Findings
- •Modulated gene expression in cerebral cortex neurons
- •Improved cognitive function and attention in elderly patients in clinical studies
- •Demonstrated neuroprotective effects in post-stroke recovery models
- •Reduced oxidative damage markers in brain tissue
Research Dosage Protocols
Cortagen is administered in short courses of 10 days, typically 10 mg daily via intramuscular injection. Repeated 2-3 times per year.
