First, when beginning to take creatine, you should start a loading phase from 7-10 days, you should tale 5g four times throughout the day. This is to load your cells w/creatine phosphate. After that you should take two 5g doses daily. This will usually maintain your creatine level. It is a good idea to mix your creatine with a fruit (grape) juice to maximize its absorbtion. Please note that if you feel extra energy after consumption, it is probably in your head. The kind of "Boost" you will feel from it will be when you are performing your lifts. It helps your muscles contract thus making the movement smoother. All this is my experience w/creatine and is not based on any kind of study. Hope this helps...........Arias
