IGF-1 LR3
Growth Factors & Muscle BuildingIGF-1 LR3 is a long-acting analog of insulin-like growth factor-1 engineered for enhanced bioavailability and prolonged action. It binds IGF-1 receptors in muscle and bone to stimulate anabolic growth, repair, and recovery. It is studied for its role in cell proliferation, muscle growth, and tissue regeneration in animal models and in vitro systems.

Post-workout injection preferred. Avoid injection around meals (insulin interference).
diet
High protein diet essential. Avoid high-carb meals around injection timing.
exercise
Heavy resistance training maximizes anabolic response.
sleep
Natural GH pulses during deep sleep synergize with exogenous IGF-1.
