This review is for both the Double Rich Chocolate 5lb Whey and the Cookies and Cream Whey in the same size. This 5lb tub contains about 70 scoops of whey with about 25 grams of protein per scoop. In my opinion this is the best whey to buy in terms of price, taste, and amount of protein per serving and total servings per container (again 70 scoops). This whey contains little else in terms of sugar or carbohydrates so you know there are no fillers. Be careful of getting cheaper Whey because they often do not actually contain the amount of protein advertised which has resulted in several lawsuits for some companies. But, Optimum Nutrition is a reliable company and, as far as I know, do not put fillers in their products to cheat you. The Double Rich Chocolate is my favorite flavor and taste exactly like chocolate milk if you mix it with milk. In regards to mixing it does not clump up too much like some other wheys or pre workout powders.
