These were the first pills I ever shot up, did them like 3/4 times right before I got on Oxy pretty much all the time..They are waaay better if you plug them, would use like half as much as you do orally, maybe even a little less. When I shot them(don't do it) we just cut off the grey part from what I remember then kinda shaved the white part into littlel pieces and let it dissolve in cold water in a spoon, probly not the safest thing, but that would be how you prepare if you plug it, just don't do the whole pill...half or a little less than half.
