IGF-1 LR3

Scientific Benefits

• Muscle Growth — Activates mTOR and PI3K/AKT pathways promoting muscle protein synthesis, satellite cell activation, and hypertrophy.
• Fat Loss — Stimulates lipolysis in adipocytes and shifts substrate utilization toward fat oxidation, supporting lean body composition.
• Extended Half-Life — 20-30 hour half-life (vs. 12-15 minutes for native IGF-1) allows once-daily or less frequent dosing with sustained anabolic signaling.
• Recovery Acceleration — Enhances satellite cell proliferation and differentiation for faster muscle repair after training.
• Anti-catabolic Effects — Reduces muscle protein breakdown under catabolic conditions including caloric deficit and overtraining.
• Connective Tissue Support — Promotes collagen synthesis in tendons and ligaments, supporting structural integrity during periods of intensive training.
• IGF-1 Receptor Binding — Retains full IGF-1 receptor affinity despite structural modification, ensuring full downstream anabolic signaling.
• Insulin Sensitivity — At physiological doses improves glucose uptake and insulin receptor sensitivity in muscle tissue.
