Product Information

Gold Standard 100% Isolate

GOLD STANDARD 100% ISOLATE contains only the highest quality whey protein which undergoes a series of sophisticated filtration processes to ‘isolate’ out excess fat, cholesterol and sugar.

The final product is a fast digesting complete protein containing no more than 1 gram of carbohydrates, less than 1 gram of fat and more than 80% pure protein per serving. We put in the hard work to assure super quality, so you can focus on achieving ambitious performance goals*

  • Hydrolyzed & Ultra-Filtered Whey Protein Isolates
  • 1 Gram of Carbs Per Serving
  • At Least 80% Protein Per Serving
  • Delicious Taste in 6 to 8 Fl. Oz. of Cold Water

I’m giving it a 3 because the isolation process isn’t mentioned, could be the the bad ion exchange method. Also the hydrolysis process isn’t mentioned either. Could be acids instead of enzymes. I think ON should follow the leads of newer fully transparent companies or they will be soon outdated!*
