MGF (Mechano Growth Factor)- Summary
- Epithalon is a synthetic tetrapeptide developed from the pineal gland extract Epithalamin by Russian scientist Dr. Vladimir Khavinson. It is one of the most researched longevity peptides, known for activating telomerase and extending telomere length — the molecular hallmarks of cellular aging.
- 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
- 2–4 hours

- Typical Dose
- 5–10 mg total per cycle
- 200–400 mcg
- Frequency
- 0.5–1 mg daily
- 1–2 times per week
- Key Benefits
- Activates telomerase enzyme, extending telomere length
- May slow cellular and biological aging
- Regulates melatonin production and circadian rhythms
- Improves sleep quality
- Powerful antioxidant properties
- May reduce incidence of age-related diseases
- Supports immune system function
- Studied for cancer prevention properties in animal models
- 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
- Injection site irritation (mild)
- Temporary sleep changes during cycle (usually improves)
- Rare: fatigue
- Muscle soreness (satellite cell activation)
- Injection site irritation
- Hypoglycemia risk (modest, less than IGF-1 LR3)
