Cortagen vs Vialox
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.
- Vialox is a synthetic pentapeptide that mimics the activity of conotoxin from cone snails, acting as an antagonist of nicotinic acetylcholine receptors at the neuromuscular junction. Similar to Syn-Ake but derived from cone snail venom biochemistry, it reduces facial muscle contraction to smooth expression wrinkles.
- Half-Life
- Short peptide half-life; gene regulatory effects persist beyond peptide clearance
- Not applicable (topical; effect duration hours)
- Admin Route
- SubQ, IM, Oral

- 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
- Reduces dynamic wrinkles from repetitive facial expressions
- Reversible muscle-relaxing effect without injection
- Smooths forehead, periorbital, and perioral lines
- Complementary to collagen-stimulating peptides
- Well-studied tolerability in cosmetic concentrations
- Can be combined with Syn-Ake for dual conotoxin/viper venom effect
- Side Effects
- Excellent safety profile
- Mild injection site reactions
- Rare: transient hypotension
- Rare: mild arrhythmia at initiation in cardiac patients
- Generally very well-tolerated topically
- Rare contact sensitivity or mild irritation
- No clinically significant systemic neuromuscular effects at cosmetic doses
