I've tried Cell Tech. Was alright.
Friends have told me NO2 was awesome. You said previously that it was alright, I believe.
Other friend told me to try Super Pump. He said he gained 3lbs of muscle in first week (dunno if I believe that) and was great, just that it gives ya bad gas.
What do you feel is the best brand out there? I'm probably going to try some Super Pump (or other powder creatine) and NO2 at the same time, and see how that works. Friend did and he gained a pretty good amount of muscle mass over a summer.
