DNP , was first used as a weight loss drug in the 1920's. As a result, the drug's use became incredibly popular because of the incredible results that it could produce!
However, in 1938, the drug was banned by the Food and Drug Association because of the number of deaths that the drug was leading to! The drug is now used to kill fungus, but among bodybuilders, the drug is showing it's ugly face once more as a weight loss supplement.
The way DNP works, is that it blocks your body from producing triphosphate, which helps your body produce energy. As a result, your body starts to burn body fat in an emergency attempt to gain energy.
Your body tries to change it's metabolism so quickly, that if you take too much DNP, your body temperature will rise and you will begin to sweat profusely. Furthermore, your internal body temperature can reach 106 degrees Fahrenheit - and you will have literally cooked your insides, and you will die.
