IGF-1 LR3

IGF-1 LR3 peptide, a recombinant analogue of Insulin-Like Growth Factor-1 engineered for extended half-life and enhanced systemic activity in laboratory settings.

What is IGF-1 LR3
IGF-1 LR3 (Long Arg3 Insulin-Like Growth Factor-1) is a synthetic analogue of human insulin-like growth factor-1 designed for laboratory research. The peptide contains an arginine substitution at position 3 and an additional 13 amino acids at the N-terminus, increasing its stability and biological activity compared with native IGF-1.

These structural modifications reduce the peptide’s affinity for IGF binding proteins (IGFBPs), allowing it to remain active for longer periods in research models. As a result, IGF-1 LR3 demonstrates extended activity and increased potency relative to standard 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.
