Cortagen is a Khavinson bioregulator tetrapeptide (AEDP) with primary effects on the brain and central nervous system. Developed at Russia's St. Petersburg Institute of Bioregulation and Gerontology, it regulates inflammatory responses in the nervous system, restores balance between pro- and anti-oxidative processes, and stimulates interleukin-2 expression. Research shows potential benefits for ischemic brain injury recovery, nerve regeneration, and reducing autoimmune reactions affecting the CNS.
Cortagen works through epigenetic regulation by penetrating cell nuclei and interacting with DNA to modulate gene expression. In the heart, it affects genes including Pass1, Hsc70, Bmp2, Wnt4, Eps15, and Eps15-rs. It powerfully regulates inflammatory responses in the nervous system, helping restore proper balance between oxidative and anti-oxidative processes. Cortagen stimulates IL-2 expression and helps regulate immune function, particularly by reducing autoimmune reactions.

Frequently Asked Questions
Is Cortagen helpful for recovery after a stroke or brain injury?
Yes, Cortagen shows research evidence for beneficial effects following ischemic brain injury with long-term improvements in neurological function. It regulates inflammatory responses in nervous tissue and promotes nerve regeneration, making it relevant for post-stroke recovery protocols alongside medical rehabilitation.
How does Cortagen differ from other brain-supporting peptides like Semax?
Cortagen targets the brain cortex specifically through IL-2 stimulation and inflammatory modulation, whereas Semax acts via BDNF upregulation for cognitive effects. Cortagen is more suited for neuroinflammation and recovery, while Semax focuses on cognitive enhancement, and they're often combined in comprehensive protocols.
Can Cortagen help with autoimmune neurological conditions?
Cortagen shows potential for autoimmune modulation through IL-2 regulation and reduction of autoimmune reactions affecting the nervous system. However, the research remains preclinical. Anyone with autoimmune conditions should consult their physician before using, as immune-modulating peptides require careful monitoring.
What's the typical protocol for Cortagen as an anti-aging agent?
Standard anti-aging use involves 10-20mg daily oral capsules for 10-20 consecutive days, repeated 2-3 times yearly. Effects persist post-cycle due to epigenetic changes in gene expression. Some users prefer injectable forms for more direct delivery, though oral bioavailability is generally good for this short peptide.
