Cortagen
Brain Peptide Bioregulator · Cortical Peptide · Cortagen Injectable
A cerebral cortex peptide bioregulator for cognitive recovery and brain ageing — Khavinson's nootropic peptide.
What is Cortagen?
Cortagen is a peptide bioregulator derived from cerebral cortex tissue, developed by the Khavinson Institute. It targets brain function specifically — aiming to restore cognitive parameters that decline with age, injury, or neurodegeneration. If you think of peptide bioregulators as organ-specific restoration signals, Cortagen is the brain's version.
The theory is compelling: as your brain ages, gene expression patterns shift away from the regenerative, plastic patterns of youth toward inflammatory, degenerative patterns. Cortagen contains peptide sequences that may partially reset cortical gene expression — supporting neuroplasticity, neurotransmitter synthesis, and neuronal survival.
Practitioners in Russia and Eastern Europe have used it for post-stroke recovery, traumatic brain injury rehabilitation, age-related cognitive decline, and neurodegenerative conditions. Western use is growing in the biohacking community, particularly among those recovering from concussions, dealing with brain fog, or seeking cognitive preservation as they age. The evidence base is promising but needs Western replication.
How Does It Work?
Cortagen peptides interact with DNA in cortical neurons, modulating gene expression related to:
1. Neurotransmitter synthesis — supporting dopamine, serotonin, and acetylcholine production. 2. BDNF and NGF expression — promoting neuroplasticity and neuronal survival. 3. Anti-apoptotic pathways — protecting neurons from programmed death. 4. Synaptic protein expression — maintaining synaptic density and communication. 5. Inflammatory modulation — reducing neuroinflammatory gene expression.
The specificity comes from the peptide sequences matching regulatory regions in brain-expressed genes — a form of epigenetic targeting.
What Does The Research Say?
Limited evidence. Mostly animal studies and anecdotal reports.
Russian clinical research: Studies in elderly patients showing improved cognitive function, memory, and attention after Cortagen courses. Used in post-stroke rehabilitation with reported acceleration of cognitive recovery.
Animal studies: Neuroprotective effects in various brain injury and neurodegeneration models.
Limitations: No Western clinical trials. All published data from Russian/Eastern European groups. Mechanism of action at the molecular level needs better characterisation. Biologically plausible but under-proven by Western evidence standards.
Reported Dosages
These are dosages reported in research literature and community reports. They are NOT medical recommendations. Always consult a healthcare professional.
Intramuscular or subcutaneous: 5-10mg daily for 5-10 day courses.
Oral capsule form also available (Khavinson bioregulator product line).
Cycles repeated every 3-6 months.
Often combined with other bioregulators (Pinealon for sleep, Thymalin for immune).
DISCLAIMER: Not approved by Western regulatory agencies. Evidence base is primarily Russian. If you have significant cognitive symptoms, get proper neurological assessment first.
Side Effects & Risks
Minimal reported side effects in Russian clinical use. Occasional: transient headache, mild stimulation or drowsiness (as brain chemistry adjusts). No serious adverse events reported in published research. Long-term safety data outside Russian studies is absent.
Legal Status by Country
Unregulated. Available as supplement (Khavinson products) or research peptide.
Research chemical or supplement. Not FDA-approved.
Available in some countries. Approved in Russia for clinical use.
Not TGA-approved.
