Build muscle, lose fat and increase nitric oxide all at once! MRI Pro-NOS is the absolute highest quality protein. Whey is the best protein for muscle growth and whey protein isolate is absorbed faster than whey protein concentrate. Now with Pro-NOS, you get whey protein isolate that is "multi-fractionated" from regular whey isolate, giving you highly refined whey protein fractions that target specific metabolic pathways in the body. Pro-NOS consists of actionos fractions that are designed to up-regulate nitric oxide synthase and VAT-burn that can help burn visceral adipose tissue (VAT) or body fat. In addition, Pro-NOS multi-fractionated whey is blended together with the highest quality whey protein concentrate so that you body absorbs the 42g of whey protein over an extended time. The biggest breakthrough in protein in 2 decades, MRI Pro-NOS is available in a variety of flavours and sizes. It gives you the power to gain muscle and strip off fat faster than ever before. Without added ingredients, just protein.
