Ive been using CEE by thermolife. Its been a good product for me. I have been taking it for about a month now. Ive made nice strength gains the last week and a half. I personaly didnt start to feel the effects until about a week ago. Ive never heard of anyones bench go up the first week from cee. So ianhockey must be lucky. most people that ive talked to sayed it usually takes about 3-4 weeks of the creatin in your system, to start to make noticable gains. Most everybody here will tell you to take purecee. It seems to be the most popular.
