IGF-1 LR3 is a lab-made version of the natural hormone insulin-like growth factor 1 (IGF-1) with a 13–amino acid extension that increases its stability and receptor binding. When it attaches to the IGF-1 receptor on cells, it activates signals that promote cell growth, development, and energy regulation. Researchers use IGF-1 LR3 to study muscle growth, tissue repair, and how cells respond to growth signals
