CEE seems to be the new thing right now. It's actually built to work best for the monohydrate nonresponders, but it works fine for plenty of mono responders as well. Actually since it's new if you compare pill form CEE dose for dose against Mono, the price comparison is not even close. Mono is much cheaper, mainly because CEE is fairly new. I've tried Omega Sports CEE Thunder and have had nice results with it. Most people prefer Omega's Thunder over the other brands, but it probably just comes down to popularity. Do some searching at the bodybuilding forums on Thunder, you'll see plenty of rave reviews about it. I've found it keeps me slightly leaner than Mono does with just as good of strength increase results, so I prefer it. I just wish the price would shoot down a bit. Good luck.
