Can i just talk about how drinking this i feel like i am on an island? I bought dymatize once or twice in the past as a splurge and now i remember why i liked this product so much and how it is worth the money. Yes its one of the pricier ones but it is so well worth it especially for the ingredients. First off the product tastes amazing whether you mix it with water or milk...i like mine with almond milk. It doesnt clump up at all, and this is one of the few proteins that i digest easily that doesnt affect my stomach. This flavor and brand is amazing! Banana is also great....i love banana everything and it tastes great when adding a bit of peanut butter

I've been using this protein for a few years now and love it. It mixes well, tastes great, and digests well. Can't ask for much more. The peanut butter flavor is amazing. Literally tastes exactly like Cap'n Crunch peanut butter cereal. I'm surprised the Cinnamon Bun flavor isn't rated higher because that's my second-favorite to peanut butter. I have 5 lbs of the banana, chocolate peanut butter, and birthday cake stored at home that I'll be trying soon. I'm sure those will be just as good as the others. I'm hoping the Rocky Road flavor comes in 5 lbs soon. I want to try it, but I buy the 5 lb tubs for better value.
