you carry around a 20ml bottle, about the size of a eye drops bottle. and a bottle of fanta or coke or whatever. Then you get a little syringe, pull out about 2-5mls and chuck it in the soft drink. theres about 1hrs worth right there. its fucked because its cheap, its made out of industrial floor cleaner and YOU CANNOT DRINK ALCOHOL WITH IT. You will die otherwise i know all this because i know heaps of ppl that use it and if you're a working dj, you just know about drugs lol
