IGF-1 LR3 (Insulin-like Growth Factor 1 Long Arg3) is a synthetic analogue of human IGF-1, a hormone structurally similar to insulin. It plays a crucial role in growth, muscle development, and cellular repair. The “LR3” variant has a 13-amino-acid extension and a substitution of arginine at position 3. These modifications increase its half-life to ~20–30 hours and reduce its binding to IGF-binding proteins (IGFBPs), allowing greater bioavailability.
Clinical studies on native IGF-1 (e.g., J Clin Endocrinol Metab, 1996) demonstrate anabolic and metabolic effects, including increased lean mass and improved insulin sensitivity.
