I tried these Pure Whey Protein Isolate shakes, they are really good. I had tried other shakes in the past that were very gritty and just plain nasty but these were actually great tasting. I had tried the chocolate Pure Whey Protein Isolate and I love it a lot . It mixed very well even with just water. You can use milk if you preferred. I also added PB2 which is a powdered peanut butter to it to give it a less richer taste. I can't have a lot of chocolate because of the richness of it . But if you love chocolate you will probably love this, I know I really like it a lot. I really like it as a replacement meal or a late night snack . It has calories at 110 , sugar 0 and protein 25 grams per serving.
