Since nobody's just come right out and said it as far as I've seen, I'll go ahead and do it: BoyMaster is currently *the only* vendor with worthwhile speed. May not be true tomorrow or next week, but it is right now. I think the number from a pleased customer who had it lab tested was 80-95% pure, if memory serves (think I saw that in the main amp review thread if you want to go looking for it). As far as I'm concerned, it really is this simple: if you're after speed, going to anybody else is a waste of time and money for now.If something doesn't get through, well, that happens sometimes. Personally it would surprise the Hell out of me if that's due to any fault of BoyMaster's, though.One last thing: I don't see it as very helpful to force somebody to wash your newly cut product just so it's "almost" as clean as it was before you "helped" them, to be frank, Methadonia. Just make sure they know you aren't making shit up when you tell them they're gonna have a not-fun time if they don't go easy at first. I don't know of any magic substance that's sterile enough to do no harm at all, doesn't need to be washed out for some other reason, and on top of it all is cheap, legal, and has a real use other than cutting drugs people want to IV. I don't pay any attention to that RoA though, so I could just be ignorant and spouting lies. Best just leave it alone, IMHO.
