I have been using AST's micronized creatine and it works great. I saw that universals creatine had creapure micronized creatine so i deceided to give it a try. I still had a little ast creatine left when i received the universal stuff, so i compared how the powders looked to each other. The universal creatine mono which says it contains micronized creapure looked a little more like table sugar with bigger particles compared to the ast stuff. The ast micronized creatine was very very fine powder almost like flour. I thought creapure was supposed to be the best monohydrate to go with? By the looks of it, it is not nearly as micronized as the ast creatine mono. Any thoughts, experiences with the two, or anyone with more in depth knowledge of it care to chime in?
