When you're pushing it to the limit in the gym, day in and day out, you put the physical stress on your body.

Everything about getting lean, strong and muscular depends on your body's ability to efficiently and effectively recuperate from the physical stress of exercise. And that's where L-Glutamine comes into play. When it comes to total anabolic support, L-Glutamine is king!
