Everyone, this is "PURE FOOD" for your body. I have gone through 2 5lb tubs so far and couldn't be more pleased. I am extremely impressed with Muscle Feast and feel fortunate there is a company like this online. I have tried several other brands including ON natural whey and RXwhey natural but this is easily the cleanest protein I have experienced. I always feel great after drinking this stuff. The tastes are fantastic, but I want to get used to the natural flavor as well, so that will be in my next order.
