ok well i never shot up before, but what i do know, is there are people out there, who cut meth with Epson salts! i dont know what its like to shoot up epson salt but i dont really wanna find out. I've heard of people cutting their stuff with all kinds of shit. but epson salt is a common one. I can say the stuff i get is pure, as it comes from the chef. but you just need to do an acetone cleaning on it, and it doesnt matter, remove whatever it was cut with. In which case, you would then know if your source is giving you good stuff or shit, or like how badly or hardly was it cut. or be like me and go, DAM! you arent shitting me! lol
