I have done it 2x, first couldnt go over 7 days, second had to stop at day 5. And didnt really see any extremely results.
And honestly it was a fxcking hell!!!!! never gonna do it again. Simply cutting cycle with test/clen with good diet in deficit, I saw way better results and felt 1000x better. DNP is crazy. couldnt sleep, no energy, felt like being in sauna all day long.
I mean its not that dangerous if you are MATURE enough and EDUCATED enough. you may try it, maybe Iam a little pussy but IMO it doesnt worth it.
As far as the chance of death goes. Most of the deaths from DNP I am aware of were just idiots taking like 3000 mg a day [normal dosage is somewhere between 200-600].
Hope it helps a bit.
