I have no idea, certainly my DNP sodium smells different from DNP powder, but there is no reason to cut DNP to lower costs, because it is incredibly cheap to manufacture. Alibaba sellers are selling DNP for industrial use along with other types of herbicides, not for fat burning pills.If it were just Sodium I would agree, but virtually all vendors on Alibaba (in my opinion) have it cut with SOdium and another compound. And its that other compound that gives THAT version of DNP a pesticide like odor.
