Nitric Oxide is produced by the body and is essential for delivering messages between the body’s cells. Nitric Oxide plays a key role in causing blood vessel vasodilation to increase blood flow, boosting the delivery of oxygen and essential nutrients to the muscles, as well as promoting growth and bulk. The amino acids L-Arginine and L-Citrulline are precursors to Nitric Oxide production. These amino acids promote the ultimate Nitric Oxide boost to increase the flow of blood that pumps valuable oxygen and nutrients to muscles, stimulating growth. Additionally, they facilitate the removal of exercise-induced lactic acid buildup, which in turn reduces fatigue, boosts endurance, and aids post-workout recovery. This supplement does things that other bodybuilding supplements simply can’t, by working on two fronts. First, it increases levels of oxygen and nutrients in the blood, boosting lean muscle growth. Second, it sustains energy levels during workouts and speeds up post-workout recovery, so you can exercise more frequently for longer periods of time.

Some customers report seeing results in as little as one week. For others, it took about a month. Results will be a bit different for each person. Some show unbelievable change right away, while others take longer.

On workout days: Take 3 capsules in the mornings before breakfast and 3 capsules 30 minutes before a workout. On rest days: Take three capsules in the mornings before breakfast and 3 capsules in the evenings before dinner. As with any type of supplement, you should not exceed the daily dosage recommendations since this can pose health risks.
