I am one of the ones for whom creatine works great. I love the water stored with the ATP makes me real hard and big for little investment. I always run 1 to 2 week cycle before a meet and it does, I mean does add strength. One warning though don't drink it with fruit juice or it will convert to creatinine--very bad for kidneys. You can cycle for 10 to 12 weeks when bulking, makes you thirsty as hell
