"There are 2 forms of DNP currently on the market, pure crystalline (100% dry) DNP, and powdered DNP (usually 5-10% moisture). The crystalline version is stronger and more effective, but more caution needs to be used while using it. It acts much faster, and the side effects also subside faster as well."
The recommend dosage are between 200-600mg per day for crystalline DNP and 400-1000mg for powdered DNP.
