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. ### Mechanism of Action 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. ### Key Benefits - Regulates central nervous system function - Powerful anti-inflammatory effects in brain - Supports nerve regeneration - Restores oxidative balance - Stimulates interleukin-2 expression - Reduces autoimmune reactions - Beneficial after ischemic brain injury - Modulates gene expression in neural tissue ### Quick Stats Typical Dose 10-20 mg daily Frequency Once daily for 10-20 consecutive days Cycle Duration 10-20 days per cycle Storage Capsules: room temperature; Injectable lyophilized: 2-8°C; Reconstituted: 2-8°C refrigerated ## Molecular Information Molecular Weight 416 Da Length 4 amino acids Type Tetrapeptide bioregulator Half-Life Minutes (short peptide); effects persist via epigenetic changes ### Amino Acid Sequence One-letter: `AEDP` Ala 1 Alanine Position 1 Glu 2 Glutamic Acid Position 2 Asp 3 Aspartic Acid Position 3 Pro 4 Proline Position 4 N-terminus C-terminus Hydrophobic Polar Positive (+) Negative (-) Modified ## Research Indications The following information is derived from published scientific literature and is provided for educational and research reference purposes only. It does not constitute medical advice, diagnosis, or treatment recommendations. These peptides are not approved for human use and are sold exclusively for in-vitro laboratory research. Neurological Support Immune Regulation Anti-Aging ## Dosing Protocols ### oral Available in capsule form for oral administration. Short peptides can be absorbed orally and reach target tissues. Typical protocol involves 10-20 day cycles, often repeated 2-3 times per year. | Goal | Dose | Frequency | Route | | --- | --- | --- | --- | | Standard protocol | 10-20 mg | Daily for 10-20 days | Oral capsules | | Maintenance | 10 mg | 2-3 cycles yearly | Oral capsules | #### Key Tips - Convenient oral administration - Short peptide allows GI absorption - Room temperature storage for capsules ### injectable Injectable form available for direct administration, bypassing GI tract. | Goal | Dose | Frequency | Route | | --- | --- | --- | --- | | Research protocol | 10 mg | Daily for 10 days | IM or SubQ | #### Key Tips - Direct absorption - Precise dosing Reconstitution Instructions ## Peptide Interactions #### Pinealon Synergistic Complementary CNS bioregulators; Cortagen for cortex, Pinealon for general brain. #### Epitalon Synergistic Often combined in comprehensive anti-aging Khavinson protocols. #### Thymalin Compatible Different organ targets; can be used in comprehensive bioregulator protocols. #### Cardiogen Compatible Part of Khavinson bioregulator family; targets different tissue. ## What to Expect During cycle Gene expression modulation begins Post-cycle Effects persist due to epigenetic changes Weeks-Months Neurological function improvements Long-term Cumulative benefits with periodic cycles ## Side Effects & Safety #### Common Side Effects - Generally well-tolerated - Minimal side effects reported #### Stop Signs - Allergic reactions - Unusual neurological symptoms #### Contraindications - Active neurological emergencies (seek medical care) - Known hypersensitivity - Pregnancy or breastfeeding ## Quality Checklist #### Good Signs - White powder or capsules - Clear solution if reconstituted - Proper packaging and labeling #### Warning Signs - Unknown source or purity #### Bad Signs - Discoloration - Unusual odor - Damaged packaging ## Research & References ### Key References 1. 2004 #### Effect of Cortagen on Gene Expression in Mouse Heart Neuroendocrinology Letters Cortagen affects expression of genes including Pass1, Hsc70, Bmp2, Wnt4, Eps15 in heart tissue. 2. 2002 #### Delayed Effect of Cortagen on Restoration of Injured Nerve Function Doklady Biological Sciences Demonstrated effects on nerve function restoration following injury. 3. 2000 #### Effect of Tetrapeptide Cortagen on Regeneration of Sciatic Nerve Bulletin of Experimental Biology and Medicine Research on nerve regeneration effects of Cortagen tetrapeptide. 4. 2020 #### Khavinson Peptide Bioregulators Advances in Gerontology Comprehensive review of bioregulator peptides and their epigenetic mechanisms.
