Optimum Nutrition Gold Standard Isolate Pre Workout Combo contains:

  • Optimum Nutrition Gold Standard Isolate 2.27KG / 5Lb

To create Optimum Nutrition Gold Standard 100% Isolate, Optimum Nutrition started by selecting only the highest quality whey protein which undergoes a series of sophisticated filtration processes to ‘isolate’ out excess fat, cholesterol and sugar. A portion of this Whey Protein Isolate is then hydrolyzed – broken down into smaller chains of amino acids – for easier digestion. 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. They put in the hard work to assure super quality, so you can focus on achieving ambitious performance goals.

Optimum Nutrition Gold Standard 100% Isolate features:

  • Hydrolyzed & ultra-filtered Whey Protein Isolate
  • 1 Gram of carbs per serving
  • At Least 80% Protein per serving
  • Delicious taste mix with cold water
  • 5.5 Grams of naturally occurring BCAAs
  • 4.3 Grams of naturally occurring Glutamine & Glutamic Acid
  • 11.4 Grams of naturally occurring Essential Amino Acids
  • Gluten free

    Great product. Taste is good when mixed with correct amount of water for the scoop. Good protein content too. This product helped me to recover from DOMS.

    I only have half a scoop as I don't have caffeine otherwise. It definitely does the trick and tastes really nice as well! Green apple hits different.

    I have it in a smoothie with banana berries and milk. Great flavour. I like how it has no sugar and only 1g of carb per serving!

    7/10 Watermelon

    Second time ever trying a pre workout. First time was some crazy one which gave my body crazy pins and needles which apparently was normal but just drove me crazy and I'd been put off ever since. This pre workout both tastes good and gives you plenty of energy for a workout (even a long, heavy leg day) without feeling like you have fire ants under your skin. Would recommend to others and this will be my go to from now on.

    7/10 Chocolate Bliss

    Instant difference in recovery and reduced recovery time as compared to the normal whey standard.
