If you guys are going to fuck with eca stack, why not just do meth? You get euphoria,incredible energy encompassed with raw damn adrenal overload of shear power beyond normal, along with it being extremely cheap and it last for about 12 -15 hours on one dose, depending on the dope head.
Before you scientist, chemist, etc chime in, lets not get on the ole card of, "That's insane, it's meth." Well, what do you think meth is made out of? Ponder that.
BTW, they prescribe meth to kids and the like. legally. LOL!
