There is a safe way and an unsafe way to use DNP. DNP can be unforgiving if it's not done to the letter.
I know BigSarge knows what he is doing, but I agree Heavy, I would not recommend this to someone who hasn't tried both ECA stacks and Clen first.
Your right dragon, sane use of DNP is okay, but the possibility of cataracs, not over-heating concerns me. Is eye cataracts from DNP usage common, or related to high doses of this chemical?
I've seen instuctions on sane use of DNP. I would feel safe going strictly by the instructions. After all, DNP was at one time a prescription weight loss drug. Problems then as now come from our ridiculous more is better and I'm too impatient to follow instuctions mentality, but the same can be said for ephedrine.
