I wonder why people are so damn afraid of DNP. As an ex med.stud. I really haven't been able to find any data indicating that it would be dangerous to use. The only problem to me is that the capsules have to be well measured and that's IMO only a problem when going for high daily dosages. Yes, you're body will produce massive amounts of free radicals, but just throw in R-ALA, vitamin-E&C, eat lots of veggies etc. and I think you would be fine.
However, I think it's positive that DNP has a reputation being dangerous. That way idiots who don't know what they're doing won't hurt themselves. To me it seems like people go for high dosages just to make sure and doing that for DNP can be very bad compared to AAS where you won't hurt yourself (in the short term that is).
Personally I think DNP is less dangerous than using AAS. You still use DNP for only a few weeks/year compared to high dosages of AAS for months and DNP doesn't have a negative feedback system, so you'll be fine almost immediately after stopping it. Also if you're a "natural" (no AAS) bodybuilder, you can bulk up and use DNP to cut down fast lots of fat without loosing any muscle. Thus you give yourself more time to actually grow instead of dieting. I myself would happily use it once a year for 10 days @ 200mg ED in the middle of a bulking period to control the amount of fat I'm gaining. However, I will never touch AAS.
The biggest downside of it's reputation is that no one has it, so you won't find any sources. Atleast that's the case in Finland.
