IGF-1 LR3 – 1mg Injection | Long-Acting Insulin-Like Growth Factor for Muscle Growth & Recovery
Peptide Calculator
Description:
IGF-1 LR3 (Insulin-like Growth Factor-1 Long R3) is a powerful, long-acting variant of IGF-1 designed to promote muscle growth, repair, and recovery. With an extended half-life compared to native IGF-1, LR3 delivers sustained anabolic effects that help increase protein synthesis and muscle cell proliferation.
IGF-1 LR3 is favored in bodybuilding and athletic communities for its potent ability to enhance lean muscle mass and improve recovery from intense training.
Key Benefits:
-
Stimulates muscle hypertrophy and cell regeneration
-
Enhances protein synthesis and nutrient uptake
-
Supports faster recovery from workouts and injuries
-
Promotes fat metabolism and improved body composition
-
Longer half-life than regular IGF-1 for sustained effects
How It Works:
IGF-1 LR3 binds to IGF-1 receptors on muscle cells, activating pathways that increase DNA synthesis and muscle cell growth. Its modified structure allows for slower degradation, ensuring extended activity in the bloodstream.
