MGF (Mechano Growth Factor)Anti-Aging & Longevity
Cartalax- 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.
- Cartalax is a tetrapeptide bioregulator (Ala-Glu-Asp-Pro) developed by Professor Vladimir Khavinson for cartilage and connective tissue. It is tissue-specific for chondrocytes and cartilaginous structures, supporting cartilage matrix synthesis, slowing degenerative changes, and promoting joint longevity. It is used in the context of osteoarthritis, joint aging, and athletic cartilage preservation.
