Laron, Z., Pediatric Endocrinology Reviews IGF-1 LR3: Direct Muscle Growth Stimulator IGF-1 LR3 binds directly to IGF-1 receptors on muscle fibers, triggering: Muscle cell differentiation and proliferation Activation of satellite cells , essential for muscle repair and new muscle fiber growth Enhanced nutrient uptake (glucose, amino acids, creatine) Because of this direct action , IGF-1 LR3 can stimulate local muscle hypertrophy without relying on systemic conversion pathways
