Optimum Nutrition Gold Standard 100% Whey is packed with the highest quality of Whey Protein Isolate (WPI) available on the market today. WPI is typically costly to use but it's considered to be the best protein that money can buy. That's why WPI is the first ingredient you'll see on the label. Along with WPI you get ultra filtered Whey Protein Concentrate (WPC). Every serving you take has a huge 24g of protein packed into every scoop to fuel your body with the nutrients you need for optimal recovery after training. You can enjoy your tub of Optimum Whey from the very first scoop to the very last. Optimum Whey flavours are top of the range and all ingredients have been instantised to ensure easy mixing with no clumping.
