MGF (Mechano Growth Factor) vs Vesilute

Side-by-side comparison of key properties, dosing, and research.

Anabolic & IGF
MGF (Mechano Growth Factor)
Anti-Aging & Longevity
Vesilute
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.
Vesilute is a tetrapeptide bioregulator (Lys-Glu-Asp-Leu) developed by Professor Vladimir Khavinson, tissue-specific for the retina and visual system. It supports retinal cell function, promotes normalization of photoreceptor protein synthesis, and is studied for age-related macular degeneration (AMD), retinal aging, and vision preservation in the elderly.
Half-Life
Native MGF: minutes. PEG-MGF: ~3 days
Short (minutes); sustained gene-regulatory effects
Admin Route

SubQ, Oral
Research
Typical Dose
200–400 mcg
10 mg per day
Frequency
1–2 times per week
Daily for 10–30 days
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
  • Supports retinal photoreceptor cell function and survival
  • May slow progression of age-related macular degeneration
  • Reduces retinal cell apoptosis from oxidative stress and aging
  • Anti-aging effects on retinal pigment epithelium
  • Potential support in diabetic retinopathy management
  • Preserves visual acuity with aging
  • Complementary to lutein, zeaxanthin, and NAD+ in ocular health protocols
Side Effects
  • Muscle soreness (satellite cell activation)
  • Injection site irritation
  • Hypoglycemia risk (modest, less than IGF-1 LR3)
  • Generally well tolerated
  • Mild injection site reactions
  • No significant ocular adverse events reported at standard doses
