great stuff, nothing else compares to it for fat loss. Before you set a dose you must first find out if it's powder or crystal because there is a difference. Powder is 100% DNP, where Crystal is 75% DNP and 25% salt. Also, I've really found that with proper diet there's no reason to break 400mg/day which is relatively safe but do TONS OF RESEARCH because it CAN kill you. If you run into a problem that you honestly can't find the answer to on this forum or in your research go over to bodybuilding . com and PM the member Concilator. He's extremely knowledgeable on DNP and I believe he's in the process of finalizing his book on it.
