Key Characteristics Mechanism of Action Pharmacological Profile Direct Receptor Activation Binds to IGF-1 receptors on target tissues Stimulates glucose uptake and utilization Promotes protein synthesis and cellular proliferation Activates intracellular signaling pathways (PI3K/AKT) Anabolic Effects Promotes muscle hypertrophy and satellite cell activation Enhances collagen deposition and tissue repair Stimulates mitochondrial biogenesis Supports bone mineralization Anti-Catabolic Action Inhibits muscle breakdown (proteolysis) Reduces protein degradation during stress Maintains lean mass during caloric restriction Supports recovery from injury or illness Key Advantages Over Natural IGF-1 Clinical Pearls: Metabolic Modulation: IGF-1 LR3 enhances insulin sensitivity and nutrient partitioning, making it particularly valuable in metabolic syndrome and insulin resistance states
