a lot of guys (myself included) notice a certain increased level of water retention simply due to increasing amount of shakes they use daily (vs. eating solid whole foods) .. not necessarily isolated to the creatine addition in the powder
real foods with solid micros are the way to go for a tighter physique, if that is what you are striving for
but just for good gp, I would not be choosing a protein powder that has creatine in it
kinda silly
