Vialox- Summary
- MGF (Mechano Growth Factor) is a splice variant of IGF-1 that is locally produced in muscle tissue in response to mechanical damage from exercise. It activates muscle satellite cells (stem cells) to proliferate and repair damaged fibers, making it specifically targeted at exercise-induced hypertrophy.
- 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.

- Typical Dose
- 200–400 mcg
- 0.005-0.05% in formulation
- Frequency
- 1–2 times per week
- Twice daily
- Key Benefits
- Activates muscle satellite cells for repair and growth
- Accelerates recovery from muscle damage
- Synergistic with IGF-1 LR3 (different mechanisms)
- Promotes muscle hypertrophy specifically at exercised muscles
- Faster recovery between training sessions
- Potential for injury repair in connective tissue
- 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
- Muscle soreness (satellite cell activation)
- Injection site irritation
- Hypoglycemia risk (modest, less than IGF-1 LR3)
- Generally very well-tolerated topically
- Rare contact sensitivity or mild irritation
- No clinically significant systemic neuromuscular effects at cosmetic doses
