- Clearer thinking
- Better memory retention
- Improved mental stamina
- Stronger neuroprotection
In weeks 1-3, research suggests Cortagen crosses the blood-brain barrier and begins activating neuroprotective genes, with studies reporting improved mental clarity. By weeks 4-6, studies show neurotrophic factor expression increases and antioxidant defenses strengthen, leading to noticeably sharper cognition and focus. Weeks 7-8 consolidate these epigenetic brain changes, with benefits often persisting for months after the protocol ends.

8-week cerebral cortex bioregulation protocol grounded in Khavinson's neuropeptide research platform
Cortagen (Ala-Glu-Asp-Pro) is a synthetic tetrapeptide bioregulator developed by Professor Vladimir Khavinson, designed to act specifically on cerebral cortex tissue. Part of the Khavinson short peptide bioregulator platform, Cortagen interacts directly with DNA promoter regions in cortical neurons to modulate gene expression related to neuroprotection, synaptic plasticity, and oxidative stress resistance.

Academician of the Russian Academy of Medical Sciences. Developer of the bioregulator peptide platform. 800+ publications, 200+ patents. Pioneering research on peptide epigenetics and aging.
Cortagen restores the gene expression profile of aging cerebral cortex tissue toward a younger phenotype. It activates neuroprotective genes that become silenced with age — a form of epigenetic rejuvenation of the brain.
10-20 mg daily for 10-20 day courses, repeated 2-3 times per year. Sublingual administration preferred for CNS-targeted peptides. Combine with Epithalon for comprehensive neuroendocrine bioregulation.

Ph.D. in Biology. Specialist in molecular mechanisms of short peptide bioregulators. Key researcher on Cortagen's effects on neural gene expression and differentiation.
Cortagen increases the expression of neurotrophic factors and antioxidant enzymes in cortical neurons. The tetrapeptide physically interacts with DNA in the nucleus — this is not a receptor-mediated effect but a direct epigenetic intervention.
Cell culture research protocols use 10-100 ng/mL concentrations. In vivo bioregulation: 10 mcg/kg body weight daily for standard course protocols.

M.D. Internationally recognized expert on neurodegenerative disease. Author of 'The End of Alzheimer's.' Pioneer of the ReCODE multi-targeted approach to cognitive decline.
Any intervention that can modulate multiple neuroprotective pathways simultaneously — neurotrophic factors, antioxidant defense, anti-apoptotic signaling — has potential value in a comprehensive cognitive optimization program.
Multi-targeted approaches to neurodegeneration should address all 36+ contributors to cognitive decline. Short peptide bioregulators like Cortagen warrant investigation as epigenetic modulators within broader protocols.

Protocolo de Dosificación
3 FasesRégimen de dosificación paso a paso compilado de profesionales líderes e investigación clínica.
Higher initial loading to achieve CNS-level epigenetic activation. Subcutaneous injection provides reliable systemic delivery for this ultrashort peptide (430 Da) which readily crosses the blood-brain barrier. Take on empty stomach.
Reduced maintenance dose sustains epigenetic changes initiated during loading. Neurotrophic factor upregulation should be established. Combine with cognitive activity for synergistic neuroplasticity.
Gradual taper permits assessment of sustained neuroprotective effects. Khavinson data shows cortical gene expression changes persist 4-6 months. Plan next course accordingly.
Supplied as lyophilized powder. Reconstitute with 2 mL bacteriostatic water per 20 mg vial = 10 mg/mL. Swirl gently until fully dissolved — do not shake. Cortagen's ultrashort size (430 Da) ensures rapid dissolution and absorption from the subcutaneous depot.
Standard Khavinson protocol: 2-3 week active courses repeated every 4-6 months. Neuroprotective effects are cumulative across courses. Allow minimum 3-month inter-course interval for epigenetic consolidation.
Lyophilized: -20°C for 24+ months. Reconstituted: 2-8°C, use within 14 days. Protect from moisture and UV light.
Subcutaneous injection into abdominal fat pad. Rotate injection sites with each dose to prevent lipodystrophy. Use insulin syringe for precise dosing. At 430 Da, Cortagen readily crosses the blood-brain barrier after subcutaneous absorption, providing reliable CNS delivery while avoiding first-pass hepatic metabolism.

Especificaciones
Cómo Funciona Cortagen
Cortagen is a synthetic tetrapeptide bioregulator that acts primarily on the brain and central nervous system. It interacts with DNA regulatory sequences in neural cells to modulate gene expression related to antioxidant enzyme production, neurotransmitter synthesis, and the balance between pro-oxidant and antioxidant processes. Cortagen has been shown to normalize cerebral cortex function, restore the balance of excitatory and inhibitory neurotransmission, and protect neurons from oxidative damage in aging models.
