IGF-1 LR3 is a long-acting synthetic analog of Insulin-Like Growth Factor-1 (IGF-1) that has been modified to extend its half-life and increase biological activity in research settings. Due to structural changes that reduce binding to IGF-binding proteins, IGF-1 LR3 demonstrates enhanced interaction with IGF receptors in laboratory models. In scientific research, compounds of this class are studied for their role in cellular growth signaling, protein synthesis pathways, nutrient partitioning, and tissue development processes.

This compound is intended strictly for laboratory and research purposes only.
