What is IGF-1 LR3?
IGF-1 LR3 (Insulin-Like Growth Factor-1 Long R3) is a modified version of natural IGF-1 engineered for enhanced potency and extended half-life. Unlike standard IGF-1, IGF-1 LR3 remains active in the body for significantly longer, making it one of the most effective peptides for cell growth, muscle development, and tissue repair.
Due to its reduced binding to IGF-binding proteins, IGF-1 LR3 delivers more bioavailable and active compound, resulting in stronger and more sustained effects.
