THE TRUE STRENGTH OF WHEY

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.

  • Whey Protein Isolate (WPI) Main Ingredient

Gold Standard 100% Whey has 4 Grams of Glutamine & Glutamic Acid in Each Serving and5 Grams of the Naturally Occurring Branched Chain Amino Acids (BCAAs) Leucine, Isoleucine, and Valine in Each Serving.”

Whitney Wiser

“This product is #1 in the industry for a reason! With all the different flavor options, you will never get bored with protein shakes. The powder mixes well and is great for pre-workout, post-workout, or any time of day that you need to get some extra protein in.”

Evan Shy

“This high quality whey protein has been a part of my supplemental strategy from day one in the gym. Uniquely valuable during “cutting” phases of programming, when macronutrient intakes are meticulously important. The right high quality protein supplement enables you to hit those detailed numbers without over consuming other nutrients.”

Rachel Ponder

“With the variety of favors I never get bored!! They all taste great and mix easily with anything from water to milk! I use it post WOD with some quick absorbing sugar for optimal recovery. My current go to is 1 scoop of the new vanilla ice cream with 2 servings of Tang- so good!!”

While it's true that ON is one of the world's largest producers of sports nutrition products, we remain focused on being recognized as the best.
