IGF1-LR3

IGF1-LR3 is a lab-made version of a natural growth factor your body produces called IGF-1 (Insulin-like Growth Factor 1). Scientists designed IGF1-LR3 to be stronger and last longer in the body than regular IGF-1, so it can be more effective in research.
It works by helping cells grow, divide, and repair themselves.
That’s why it’s often studied in areas like: Muscle growth and recovery, Wound Healing, Tissue regeneration, and Nerve protection.
What makes IGF1-LR3 special is that it doesn’t get blocked by the body’s natural “brakes” (called binding proteins), so it stays active longer and reaches more cells.
Researchers use it in lab settings to better understand how growth and repair happen in the body. It’s not for human use, but it’s a powerful tool for studying how cells grow and heal.
