Nitrix 180ct by BSN The New Muscle Enhancing Phenomenon That Will Change A CRTS (Controlled-Release Technology & Support System):Methocel (Micro-Polymer Hydrophilic Ether Matrix): Methocel is a controlled-release technology produced by Dow Pharmaceutical (www.methocel.com). Methocel enables Nitrix to support prolonged (several hours) increases in whole-body nitric oxide (NO) production. This is essential, as NO has a half-life of only a few seconds or less. World Class Nutrition has the lowest price.L-Arginine Alpha-Ketoglutarate (AKG): Arginine is an amino acid and a precursor to nitric oxide (NO). Science suggests that chemically bonding AKG to arginine may enhance its conversion into NO, thereby more powerfully increasing blood NO levels. NO stimulates vasodilation (i.e. opening of blood vessels) and may be involved in the muscle hypertrophic (growth) response to exercise.Phosphoplexx (Calcium Phosphate, Di-Potassium Phosphate, and Sodium Phosphate): Phosphates enhances muscle phosphocreatine production, and muscle strength and endurance.NEW TO FORMULA - CEM3 (Creatine Ethyl Ester Malate): CEM3
