Click Label To Enlarge ETHYLSTEROL ETHYLOSTEROL™ contains three proprietary blends that will have your muscles blown up. Ingredients such as Di-Arginine Malate and Arginine Alpha-Ketoglutarate are Nitric Oxide (NO) precursors. NO is responsible for cell communication. Increased synthesis of nitric oxide controls the muscles surrounding the blood vessels and inhibits platelet aggregation, which is responsible for blood viscosity. Creatine Ethyl Ester has been added to induce explosive release of Creatine in muscle cells and to help incite a dramatic cytoplasmic cellular expansion and seriously improve rapid bio-delivery of ATP. Citrulline Malate increases ATP (Adenosine Triphosphate, the major energy source within the cell) production and phosphocreatine recovery after exercise. Citrulline Malate can also benefit athletes - by increasing aerobic energy production. ETHYLOSTERON™ is the Next Generation’s Nitric Oxide (NO) Booster, which help you to become bigger then you think.
