DNP is a nasty cutting drug I wouldn't recommend anyone take. In bodybuilding the use of DNP is typically done in the amateur level because people at that point are less discapilined at dieting and contest prep. DNP is used as a way to cut corners to drop fat instead of dieting or the use of less harsh drugs. There's a lot of great info on reddit about the 'safe' use of DNP https://www.reddit.com/r/steroids/wiki/dnp but unlike every other steroid or ancillary that is used in bodybuilding, DNP is the only one that wasn't every intended to actually be consumed by a living creature. It's a straight up poison.
