I like the crystalline stuff rather than the powdery stuff because when I mix creatine with a juice the powdery stuff tastes worse, probably because the crystals just float past your tongue and you barely taste it.

My fav way to take it is put a tablespoon of crystals in about 3 fingers of juice, swirl the cup with the wrist and sip, swirl and sip, swirl and sip, until its all gone.
