Flooding your body with the powerful nitric oxide precursor primes you for enhanced pumps, blood flow and nutrient delivery.Scientifically Advanced FormulaWhen you train, your body releases calcium in the endothelial cells that line your blood vessels. This causes then enzyme nitric oxide synthase to create nitric oxide from available L-arginine. As the nitric oxide leaves the endothelial cells, the blood vessels relax, causing vasodilation. By supplying a massive dose of L-arginine to your body, Platinum 100% L-Arginine helps trigger extreme nitric oxide production for superior vasodilation effects and massive pumps.‡MuscleTech is America's #1 Selling Bodybuilding Supplement Brand based on cumulative wholesale dollar sales 2001 to present.Container size: 100 capletsServings per conatainer: 50Serving size: 2 capletsAmount Per Serving (2 caplets) %Daily ValueL-arginine (as L-arginine HCI) 1,000 mg ††Daily Value not established.Other Ingredients:Microcrystalline cellulose, hydroxypropylcellulose, stearic acid, coating (polyvinyl alcohol, titanium dioxide, polyethylene glycol, talc), silicon dioxide, acesulfame-potassium.Suggested Use:Take 1 serving (2 caplets) with a glass of water once daily.Warnings:For adults use only.
