IGF-1 LR3 (Long R3 Insulin-like Growth Factor 1) is a synthetic polypeptide growth factor and a modified form of natural IGF-1. The "LR3" in its name originates from the amino acid sequence modification—adding a long-chain arginine sequence at the N-terminus, which significantly alters its biological activity, stability, and affinity for binding proteins compared to natural IGF-1.

• Structural Advantage：Through amino acid sequence modification, IGF-1 LR3 has a longer half-life (retention time in the body) and reduced binding to IGF-binding proteins (IGFBPs), allowing it to more efficiently bind to IGF-1 receptors on target cells and exert biological effects.
• Stability：Compared to natural IGF-1, the LR3 variant is more stable in serum and tissues, less prone to degradation, and easier to handle in research experiments.
