Depends where you get it from. I have had some that taste like ass. Canadianwhey.com has the best tasteless protien I have ever used, and it is also the best mixing isolate I have used. I have used allthewhey and it does not mix even close to Canadianwhey. With Canadianwhey, literally 2 swirls with a spoon and the stuff is mixed. As long as you drink it with something that has some flavour its not bad at all. I drink mine with dextrose and kool-aid. If you drink it with water, or regular milk, its pretty bland tasting and boring.
