Cortagen

Cortagen

Also known as: Cortagen tetrapeptide, AEDP

Overview

Key Facts

Primary Goal: Research and therapeutic applications of Cortagen

Penetrates cell nuclei and interacts with specific DNA sequences to regulate gene expression (epigenetic bioregulation model). Modulates expression of genes involved in neuronal survival and synaptic plasticity in the cerebral cortex.

Dosing Information

Half-Life

Short (minutes as intact peptide; epigenetic effects persist)

Typical Dose

10–50 mcg

Frequency

once daily

Cycle Length

10-20 days, repeated 2-3 times per year

Administration Routes:
subcutaneousoral

Benefits

  • Potential neuroprotective effects through gene expression modulation
  • Supports cerebral cortex function in ageing models
  • Epigenetic regulation of neuron-specific gene activity
  • Extremely low dose requirement
  • Part of the Khavinson bioregulator peptide family with decades of Russian research

Side Effects

Very limited adverse event data availablemild
Occasional mild headachemild
Rare injection site irritationmild

Mechanism of Action

1

Penetrates cell nuclei and interacts with specific DNA sequences to regulate gene expression (epigenetic bioregulation model)

2

Modulates expression of genes involved in neuronal survival and synaptic plasticity in the cerebral cortex

3

Part of the cytomaxin/cytogen class of peptide bioregulators hypothesized to restore organ-specific gene expression patterns

4

Antioxidant effects through upregulation of endogenous antioxidant enzyme expression

Contraindications

Do not use this peptide if any of the following apply:

  • Pregnancy or breastfeeding
  • Active CNS infections
  • Known hypersensitivity to short peptide bioregulators

Duration2-4 weeks

Research Summary

Preclinical
100 studies

Cortagen is part of Professor Khavinson's bioregulator peptide programme, which has produced over 100 published studies on short peptides that modulate gene expression in tissue-specific ways. Research on Cortagen specifically has been published in Russian biomedical journals and the Bulletin of Experimental Biology and Medicine, demonstrating effects on cortical neuron gene expression patterns and neuroprotection in ageing models. The bioregulator hypothesis — that short peptides can epigenetically restore youthful gene expression — remains an active area of research, primarily in Russia and Europe.
