I started to change my view on creatine ethyl ester after reading 
    this
 Study. I took it on/off for about a  year (the evox v4) never being sure if it was doing much. That's just my experience. The theory behind creatine ethyl ester makes logical sense but according to that study done with 30 men for 7 weeks comparing creatine monohydrate, creatine ethyl ester, and a placebo found that monohydrate was better absorbed into muscles. 10g of CEE was taken per day after the loading phase.
The study concluded that creatine ethyl ester didn't show any benefit over monohydrate with increase in muscle strength or performance, and that much of the creatine ethyl ester was being degraded to useless creatinine.
Another 
    Study
 indicated that CEE's half life is too short to effectively reach muscle cells in its ester form.
I'm not a fan of the bloating from monohydrate that Koe mentioned and for sure if you get monohydrate use a creapure, but personally I have not found CEE to be more effective at all. After quite a bit of looking I have not found any legitimate study to prove otherwise. Only here say and unverified marketing strategies. I'd gladly change my view if someone can post any evidence for CEE?
