IGF-1 LR3 is a modified form of insulin-like growth factor-1 designed with an extended half-life and reduced binding to IGF-binding proteins, allowing for greater bioavailability.
It promotes cellular growth, protein synthesis, and muscle development by activating the IGF-1 receptor and downstream anabolic pathways.
IGF-1 LR3 also supports tissue repair and recovery by enhancing nutrient uptake and cell proliferation. Its prolonged activity provides a sustained effect compared to native IGF-1.
