Mike Burton, the guy who runs American Chemical Supply, is currently in jail awaiting trial on charges that he violated the Federal Controlled Substance Analog Act. It would be highly unwise of you to try ordering from there right now. Either you'll just send the money to a dead account, or if the feds hijacked the site, you'll end up being made a witness for them, saying you were ordering the chemical for recreational use.
Don't be stupid. If you're going to order, order from overseas, as any American site is no longer safe. Hell, I would seriously advise not ordering research chems at all, at least until Burton's case is decided. It will set a precedent for whether or not someone with his kind of disclaimer can get away with doing what he was doing.
Though I don't expect it from most people who use drugs (as a former drug user, myself, I've seen enough people who don't bother to think before acting, even while they risk their bodies and their freedom), I implore you to please use your brain.
