IGF-1 LR3 is a long-acting analogue of insulin-like growth factor-1 widely studied in scientific research involving cellular growth, regeneration, and metabolic signaling pathways.

Due to its extended half-life compared to natural IGF-1, IGF-1 LR3 is frequently investigated in laboratory models examining tissue development, protein synthesis pathways, and cellular proliferation.
