MGF (Mechano Growth Factor)- Summary
- Liraglutide is a long-acting GLP-1 receptor agonist approved for type 2 diabetes (Victoza) and chronic weight management (Saxenda). It reduces appetite, slows gastric emptying, improves insulin secretion, and promotes weight loss of 5–10% in clinical trials.
- 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
- ~13 hours (once-daily dosing)
- Native MGF: minutes. PEG-MGF: ~3 days

- Key Benefits
- Promotes weight loss (5–10% average)
- Reduces appetite and caloric intake
- Improves blood glucose control (HbA1c reduction)
- Reduces cardiovascular events in T2DM (LEADER trial)
- Slows gastric emptying
- FDA-approved for T2DM and chronic weight management
