DNP does work, but man the sides are alot worse then Clen IMO.... I can't stand being so hot, and not being able to get cool no matter what... I remember doing DNP in the middle of the winter, and having to go outside in 20 degree weather, wind blowing and everything, still couldn't get totally cool.... It just drove me nuts. Not to mention trying to sleep, and soaking the fucking sheets.... DNP is chemically similar to TNT, that should scare you right there. Not to mention that DNP prob ruins your metabolism.... I guess everyone likes what they like, but for me, I'd take Clen over DNP any day....
