IGF-1 LR3 1mg (Insulin-like Growth Factor-1 Long R3) is a highly advanced peptide known for its ability to stimulate cellular growth and protein synthesis. Unlike regular IGF-1, the LR3 variant has a longer half-life, allowing for sustained anabolic activity in the body.
This peptide supports:
-
Enhanced muscle growth and strength
-
Faster recovery from intense workouts
-
Improved fat metabolism
-
Increased cellular regeneration and repair
IGF-1 LR3 works by activating IGF-1 receptors in muscle tissue, which accelerates protein synthesis and promotes muscle hypertrophy. It is commonly used in cutting and bulking cycles to maximize lean muscle gains while reducing recovery time.
Dosage & Usage:
-
Typically administered via subcutaneous injection
-
Standard research doses vary, often starting at 20–50 mcg per day
-
Should be used under professional guidance
IGF-1 LR3 1mg is a reliable choice for athletes and bodybuilders looking to boost performance, enhance lean muscle development, and optimize recovery.
