First off, I'm for DNP. Hell I may be on it right now.
Most of the scary info seems to be more myth than fact. And lets face it DNP is to people that can't cut up that well as steroids are to people that can't gain mass as well as they like.
As for lethary and strength. Yes I don't sleep well, yes I sweat like a mofo. Yes for two weeks life is rather grose, but for whatever reason I don't lose strength and my workouts don't suffer.
Most likely because I did my homework, protected myself, drink as much water as I can and followed all DNP rules like my life depends on it, because it does.
I would advise you to go to a furum that has more people who have used DNP and can share there experiance rather than listening to opinions of peole who wouldn't touch it with a ten foot poll. Reason would dictate that all those people who seem to have used it more than once probable wouldn't if it were that unpleasant or if they died.
As for dose I like 400mg of the gen 2 caps.
