We are looking at 150-200 us dollars a gram for 4-dimethylaminorex (the average dose is 10-20mg) and it lasts from 6hr to 14hr. Not sure on the pure amphetamine, but, It will be around what SR has it listed. (For the best of the best stuff)...the reason I don't know yet, is that I haven't seen pure amphetamine.Some claim its pure, but its not. we'll probably start off with small sample packs to get some feed back before we set on a price. But as most of you know, I don't gouge customers. I try to bring a good product at descent prices. So, you can count on that...
