IGF-1 LR3 is a long-acting analog of insulin-like growth factor-1 with reduced binding to IGF binding proteins, extending its activity. Research focuses on muscle protein synthesis, neural repair, and cellular growth.

Research Focus:

• Muscle anabolism and recovery
• Neuroregeneration
• Cellular growth and differentiation
