I've generally thought that there isn't a significant difference between cyclin creatine and not, but Prime Rib said it in an interesting manner.
What i learned from Sports Restoration and Massage is that with any restoration measure whether massage, showers, vitamin preparations, etc your body will in essence adapt to the specific restoration measure. If you look at creatine in that light, then your marginal benefits of creatine will go to nill after a while, whereas you could take it for a while then stop for a while, 1month +, and then reintroduce your self to it later.
