Cortagen vs VIP
Side-by-side comparison of key properties, dosing, and research.
- Summary
- Cortagen is a synthetic tetrapeptide (Ala-Glu-Asp-Pro) developed at the St. Petersburg Institute of Bioregulation as a cardioprotective and vascular bioregulator. It stimulates repair of cardiac and vascular tissue, with demonstrated benefits for coronary artery disease, atherosclerosis, and cardiac aging.
- VIP is a 28-amino acid neuropeptide with profound anti-inflammatory, vasodilatory, and immunomodulatory effects. It plays a critical role in gut motility, circadian rhythm, and immune tolerance. Used therapeutically for CIRS (Chronic Inflammatory Response Syndrome), MCAS, and inflammatory conditions.
- Half-Life
- Short peptide half-life; gene regulatory effects persist beyond peptide clearance
- ~2 minutes in plasma (rapidly degraded by peptidases); intranasal delivery may extend local CNS effects
- Admin Route
- SubQ, IM, Oral
- Intranasal, SubQ, IV

- Typical Dose
- 10 mg SC or IM daily
- 50 mcg (4 sprays of 12.5 mcg each)
- Frequency
- Once daily
- 4x daily
- Key Benefits
- Cardioprotective — protects cardiac tissue from ischemic damage
- Promotes cardiac regeneration and repair
- Improves vascular endothelium function
- Reduces atherosclerosis progression
- Anti-aging effect on heart muscle cells
- Improves cardiac output and exercise capacity
- Reduces oxidative stress in cardiovascular tissue
- May reduce arrhythmia frequency
- Potent anti-inflammatory for CIRS and mold illness
- Improves pulmonary hypertension symptoms
- Regulates gut motility and IBS symptoms
- Modulates circadian rhythm and sleep quality
- Reduces mast cell activation (MCAS)
- Improves cognitive function in neuroinflammatory conditions
- Vasodilatory — reduces vascular resistance
- Side Effects
- Excellent safety profile
- Mild injection site reactions
- Rare: transient hypotension
- Rare: mild arrhythmia at initiation in cardiac patients
- Facial flushing (transient, intranasal)
- Mild nausea
- Headache at initiation
