Standard monohydrate always made me carry water weight so I quit using it. My friend had the same problem. I'd definitely use micronized if I used the mono.
There are other esters which aren't supposed to cause that problem because they store the water more in the muscle cells. I just ordered a few of them to try, purple-k, green magnum, and rich gaspari's size-on. I'm not sure about size-on since it still has monohydrate in it but I just got a sample pack to try superpump too so wont be out much if I dont like it.
