I suggest you to run a search for "DNP." You'll find a ton of info. In fact, do this on multiple discussion boards, and go to some of the more informative websites about it and read up. DNP is NOT something to use w/out being informed. As far as your initial question, there is no comparison b/w the fat loss efficacy b/w DNP vs. Clen, but then again, Clen can't kill you if used improperly.
