Description

IGF-1 LR3 (Insulin-Like Growth Factor-1 Long Arg3) is a modified form of IGF-1 designed for extended stability and activity in research settings. Structural changes to the native IGF-1 molecule increase its resistance to binding proteins, allowing it to remain active for a longer duration compared to standard IGF-1.

In research models, IGF-1 LR3 has been studied for its role in cellular growth signaling, nutrient partitioning, and tissue regeneration pathways. IGF-1 is a key mediator of growth hormone signaling and plays a central role in anabolic and metabolic processes at the cellular level.

Due to its prolonged activity, IGF-1 LR3 has been widely examined in studies related to muscle cell proliferation, recovery mechanisms, and metabolic efficiency, making it a compound of interest in performance, repair, and longevity-focused research.
