Well as far as the fat burning goes DNP is awesome... I used it a total of 10 times over the past 2 years or so...
BUT....
My sides were terrible and i mean terrible. Sometimes i would just get the heat associated with it. Sometimes I would get a case of a bad flu-like feeling. Fever, head and bodyaches. Once i ate a bunch of chicken and took some DNP, i didn't even fully digest the chicken and i threw up like 5 hours later, there was no liquid or anything, just my little bites of chicken.
Another time, i didn't swallow the capsule all the way and it dissolved in my throat. And i had a terrible burning sensation in my throat for 2 days and couldnt get it to stop. Also got vey bad hypoglycemic like feelings(now i have hypo but prob from slin)
And to top it all up it fucked meup in the long run. Before i touched DNP, i never had sweating problems. Now if i have a sweater and jacket on in 30 degree weather i sweat. I run the ac in my car full blast when its 70 degrees out and my back drenches. It gave me terrible sweating problems
All in all, stay away from it... I had just as good effects combining ephedrine, norephedrine, caffeine, yohimburn and an ALA/CLA/GLA stack... I did that for 6 weeks and people were like WOAH and i was like DAMN
