OPTIMUM NUTRITION 100% Whey Gold Standard, 5 lbs

Whey Protein Isolates (WPI) are the purest form of whey protein that currently exists. WPIs are costly to use, but rate among the best proteins that money can buy. That's why they're the first ingredient you read on the Gold Standard 100% Whey™ label. By using WPI as the primary ingredient along with premium ultra-filtered whey protein concentrate (WPC), we're able to pack 24 grams of protein into every serving to support your muscle building needs after training. ON's attention to detail also extends to mixability. This superior quality powder has been instantized to mix easily using a shaker cup or just a glass and spoon. There's no doubt that this is the standard by which all other whey proteins are measured.
 
IGHER PROTIEN PERCENTAGE. ON's 100% Whey Protein has always been a leader in this respect. With 23 grams of protein in just a one ounce serving, it's nearly 81% protein by weight! 

Every serving supplies even MORE low, moderate, and high molecular weight, biologically active WHEY PROTEIN MICROFRACTIONS including Alpha-lactalbumin, Glycomacropeptides, Beta-lactoglobulin, Immunoglobulin G (IgG), Lactoferrin, lactoperoxidase, and various growth factors. 

Over 4 grams of GLUTAMINE & glutamine precursors as well as 5 grams of BCAAs (leucine, isoleucine, and valine) in each scoop!
 
Whey protein is popular with active adults because it digests rapidly and is a rich source of amino acids for muscle recovery. Whey protein isolates are the purest form of whey and the primary ingredient in Gold Standard 100% Whey. Each serving provides 24 grams of rapidly digesting whey protein with low levels of fat, cholesterol, lactose and other stuff you can do without. There's no doubt this is the standard all other proteins are measured against.
