Starting line is considered our "Pre-Workout" although we don't like to use that phrase as most Pre-Workout's are loaded with fillers, sugar, stimulants, and "energy blends". Ours, however, is just packed with Amino Acids that play a significant role in allowing your blood to flow optimally throughout your body, giving your muscles the proper energy to perform at a high level. Increasing your nitric oxide levels means your body can use less oxygen to perform the same task, which keeps you running longer, and at a high level. It's like upgrading your engine to allow for better MPG. Along with the L-Arginine and L-Citrulline, we added 800mg of Beet Root Powder to further increase nitric oxide output so your body will be firing on all cylinders.
