hey ive tried a few sites and got different stuff from all, one sent crystal stuff, quite big crystals not quite the size of salt, really easy to divide, smelled strong and tasted foul, also seemed to be more toxic. the other site send stuff that had smaller crystals and a bit powdery, more clumped together and harder to divide into small lines, had next to no smell tasted not 2 bad and didnt hurt as much if snorted. which do u reckon is more pure, the second lot was cheaper so im guessin the 1st lot, although is seemed to make people worse the next day and more toxic!
