These modifications result in: Increased potency (~2-3x stronger than natural IGF-1) Extended half-life (~2030 hours) Reduced binding to IGF Binding Proteins (IGFBPs), allowing more active IGF-1 to interact with receptors Benefits of IGF-1 LR3 Systemic Effects Circulates throughout the body, promoting overall muscle growth
