Anabolic protein for recovery and muscle gains. MyProtein have gone from a small business set up and operated in their founder's home to one of the biggest sports nutrition brands around. Impact Whey Protein is their signature product, a WPC80 or whey protein concentrate 80. What this means is that Impact Whey is approximately 80% protein for every 100% of powder although flavoured versions will be a little less. With a wide range of flavours allied to a high protein percentage and low price, Impact Whey is a great choice for those seeking a protein which is absorbed quickly but who do not need the extra protein content of an isolate or isolate/concentrate blend.
