What is IGF-1 LR3

IGF-1 LR3 (Long Arg3 Insulin-Like Growth Factor-1) is a synthetic counterpart of human insulin-like growth factor-1 created specifically for laboratory study. The peptide has an arginine substitution at position 3 and an extra 13 amino acids at the N-terminus, making it more stable and biologically active than native IGF-1.

These structural changes diminish the peptide’s affinity for IGF binding proteins (IGFBPs), allowing it to be active for extended periods of time in research models. As a result, IGF-1 LR3 has improved activity and potency compared to conventional IGF-1.

IGF-1 LR3 peptide benefits are commonly explored in research settings investigating:

• May support increased lean muscle mass
• Accelerates injury recovery time
• Enhances endurance and performance
• Helps post-workout muscle recovery
• May support body fat reduction pathways
• Enhances protein synthesis in muscle tissue
• Supports nutrient partitioning research and metabolic signaling
• Investigated for tissue repair and regenerative mechanisms

These findings refer strictly to laboratory investigations and are not medical claims.
