IGF-1LR3 0.1mg

IGF-1 LR3 (Insulin-like Growth Factor-1 Long Arg³) is a synthetic, modified version of human insulin-like growth factor-1 that stays active in the body much longer than the natural hormone. 

How It Works

• Natural vs. Synthetic: Natural IGF-1 has a short half-life of less than 20 minutes before binding proteins neutralize it. IGF-1 LR3 has 13 extra amino acids and an arginine substitution. 
• Longer Activity: This modification stops binding proteins from attaching to it, extending its active half-life in the bloodstream to 20–30 hours. 
• Cellular Signaling: It binds directly to IGF-1 receptors to promote protein synthesis, tissue repair, and cellular growth (hyperplasia and hypertrophy). 

Potential Uses and Research

• Muscle Recovery: Studied for its potential to help repair muscle tissue, tendons, and ligaments after intense stress or injury.
• Nutrient Partitioning: Known in fitness spaces for improving how muscle cells absorb glucose and amino acids.
