Creatine Cycle
As a student of Exercise Physiology I have learned that it is important to cycle any supplement, even those that the body naturally produces. The reason being, if you fail to cycle the body will become accustom to the excess amounts of the supplement (i.e. creatine) that we ingest and will no longer produce. The best cycle is either 2:1 or a 1:1 cycle (i.e. 2 months on 1 month off or 1 month on 1 month off). Some disagree saying it's a waste of money to cycle creatine since it's a natural substance which is wrong. The body only has small levels of creatine that are depleted with even simple movements such as walking, where as if you supplement it keeps the levels at 100%. However, as with any supplementation any excess amounts will just be excreted as waste through urine (usually) which could tax the kidney's (even more reason to cycle). Also, research has shown that creatine is the only supplement that is proven to work and is safe if used properly (just an added tidbit). Hope this helps.
