I'm personally an aggressive lifter and worked out for years with a guy who does fitness events..etc. I know creatine works, I just don't like how it bulks me up almost too fast. That was all I was saying, even though I know you are addressing more posters than myself.
Without a doubt it has been one of the most used natural lifting supplements for 20 years now. It works. You have to cycle it, and your body can build up a tolerance as well.
