Description
IGF-DES (Insulin-Like Growth Factor-1 DES)
Overview
IGF-DES is a truncated form of IGF-1, which has 3-10 times higher potency in muscle growth and repair due to its enhanced receptor binding and reduced binding protein affinity.
Key Benefits:
✔ Rapid muscle growth and hypertrophy
✔ Increased nitrogen retention and protein synthesis
✔ Enhances endurance and recovery
✔ Works locally at the site of injection
Mechanism of Action:
- IGF-DES bypasses IGF binding proteins, increasing its potency in muscle and tissue growth.
- Stimulates hyperplasia (new muscle cell formation), unlike regular IGF-1, which only promotes hypertrophy.
