MGF (Mechano Growth Factor)- Summary
- SNAP-8 is a synthetic octapeptide cosmetic ingredient that reduces the depth of expression lines and wrinkles by competitively inhibiting the SNARE complex involved in acetylcholine release at neuromuscular junctions, providing a topical 'Botox-like' effect.
- 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.
- Half-Life
- N/A — topical application; local effect duration depends on formulation
- Native MGF: minutes. PEG-MGF: ~3 days

- Typical Dose
- 3–10% concentration in formulation
- 200–400 mcg
- Frequency
- 1–2x daily
- 1–2 times per week
- Key Benefits
- Reduces depth of dynamic expression wrinkles
- Smooths forehead lines, crow's feet, glabellar lines
- Non-invasive topical Botox alternative
- Can be incorporated into serums, creams, eye contour products
- Reduces muscle contraction without paralysis
- Improves skin texture and firmness over time
- Complements other anti-aging peptides (Argireline, Matrixyl)
- 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
- Side Effects
- Generally excellent tolerability
- Rare: mild redness in sensitive individuals
- Not suitable for injection (topical use only)
- Muscle soreness (satellite cell activation)
- Injection site irritation
- Hypoglycemia risk (modest, less than IGF-1 LR3)
