Forgot one which will probaply be my favourite if I could get my hands on it, Palladone XR, ofcourse the strongest version, the 32mg ones. Though they aren't available here anymore, but the 24mg still are, and when you crush up the time release beads in one 24mg capsule, your left with just a small amount of powder to snort, and I'm pretty shure that even though it has a low nasal bioavailability, high doses will be very nice, and you do have wopping doses if you have even just a few of those capsules. Palladone might just be the king of all :D
