Optimum Nutrition Gold Standard Gainer is built on a foundation of complete dairy proteins, mostly from isolate sources. The carbohydrate blend includes oat, pea and potato and the fats include medium chain triglycerides, chia and flax. Obviously, this is not your typical gainer formula. ON took it a step further by making it easy to mix up in a shaker cup. No blender needed. This is the new Gold Standard for weight gain.  Gold Standard Gainer is powered by a high-quality Protein blend, including the fast absrobing Whey Isolate and Hydroslate. These Proteins are high in both BCAAs and Essential Amino Acids, meaning they're ideal for recovery and new muscle growth.

Perhaps the best PWO I have experienced yet, on a double serve it will give you amazing pumps and a long lived buzz, sometimes get the tingles on 2 scoops, however it just makes me want to train more. The taste was amazing for a PWO (Blue Rasberry), wasn't chemically, however it was quite strong but that hasn't put me off it, will defiantly be getting some more!!!
