Optimum Nutrition 100% Whey Gold Standard - 2.27kg


It's a decent product but I'm going to switch to Bodybuilding Warehouse's own brand whey from now on - the BBW whey tastes better, is incredible quality and miles better value. Why pay more?

Optimum Nutrition 100% Whey Gold Standard - 2.27kg

BBW Whey 80 Is Better And Cheaper

Been using ON 100% Whey for years now, but last month I decided to take Bodybuilding Warehouse up on one of their offers and tried their own Pure Whey Protein 80. What can I say? I preferred the BBW Whey and 2kg was only £25 which is half the cost of the Optimum, but BBW's tasted better, mixed better, and the protein content and low sugar was the same. Won't be going back - BBW Whey 80 is the way forward.

Optimum Nutrition 100% Whey Gold Standard - 2.27kg

Superior Quality Whey Blend

Gold Standard Whey is a top whey blend that includes Whey Concentrates, Isolates and even Hydro Whey which is an ideal blend for post workout recovery. This protein powder has been a staple product that I have used many times in the past and I feel is only rivaled by BBW Premium Whey Probiotic. I have tried this protein powder in the Chocolate Mint, Rocky Road and Mocha Cappuccino Flavours, all have mixed very easily in a glass of water with a spoon or fork in 250 - 300 ml of water or skimmed milk depending on if i am cutting or bulking. Out of the 3 Mocha Cappuccino has to be the best whilst the others get a solid 9.5/10 for overall flavour quality. New customers this is a top notch premium value product that will aid your progress in building and maintaining lean muscle mass after intense weight based workouts and allow for you to meet your target protein requirements. to get 5% OFF your order Use My Referral Code: 7456757
