Supplementing with L-arginine can help improve your workout performance. Increasing nitric oxide helps improve blood and oxygen flow to the muscles. This makes pumping muscles easier, especially if L-arginine is boosted before exercise.

Very excellent. Two pills before exercise with a cup of plain coffee. It gives you a boost and stamina, highlights the veins and burns fat.

L-arginine is an amino acid that acts as a vasodilator. It is converted into nitric oxide in the body. Nitric oxide causes blood vessels to dilate to improve blood flow. The increase in nitric oxide helps improve blood and oxygen flow to the muscles. This makes it easier to pump muscles, especially if L-arginine is used before training.
