MGF (Mechano Growth Factor)- Summary
- Syn-Coll is a palmitoylated tripeptide (Palmitoyl Tripeptide-5) that mimics thrombospondin-1 to activate TGF-beta, the primary growth factor driving collagen synthesis in the dermis. It is one of the most mechanistically direct collagen-stimulating peptides in cosmetic formulations.
- 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
- Extended (lipid depot in stratum corneum)
- Native MGF: minutes. PEG-MGF: ~3 days

- Typical Dose
- 0.005-0.05% in formulation
- 200–400 mcg
- Frequency
- Once or twice daily
- 1–2 times per week
- Key Benefits
- Directly activates TGF-beta for potent collagen synthesis stimulation
- Increases dermal thickness and firmness
- Reduces depth of wrinkles and fine lines
- Improves skin elasticity
- Clinically validated in collagen induction studies
- Complementary to retinoids or vitamin C
- 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 well-tolerated
- Rare mild irritation at high concentrations
- Possible sensitivity in individuals with inflammatory skin conditions
- Muscle soreness (satellite cell activation)
- Injection site irritation
- Hypoglycemia risk (modest, less than IGF-1 LR3)
