I have extensive experience with BZP. I did just about everything to it. Banged it, IM'ed it, smoked it, snorted it (burns more then anything I've ever seen), reacted it to gas the powder out (was liquid initially), did that cigarette thing someone was talking about with cocaine, smoked it with tin foil, glass bulb, and of course ate it. When you got 50 grams of the shit you wanna get SOMETHING out of it.
Its fucking pure trash, makes you feel like shit. Thats pretty much all it does. I've done insane amounts of it with absolutely no pleasurable effects. I figured I would at least get a little rush from mainlining it, nothing.
So I got rid of it. And walked away with 4000% profit. And its legal.
Don't bother with it. Make Meth.
