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.
