From Lab to Muscle: The Journey of IGF-1 LR3 in Sports Nutrition
IGF-1 LR3, or Insulin-like Growth Factor-1 Long Arg3, is a synthetic analog of IGF-1. Engineered to include an extended chain of amino acids, its modification increases the half-life, allowing for longer-lasting effects on muscle growth and recovery. Athletes and bodybuilders often research it for performance enhancement, but its use should be cautious due to potential risks.
