Thats not really the kind of information that is passed along through these forums, in terms of where to go to get it/order it.
However, there is a will website that lists a great many reaserch chemicals and what is known about them. It's called psychonaught wiki. You may be very surprised to find out ketamine is very closely related to classic PCP, and there are others. That website can help you figure out what to look for, but you are on your own in finding out where to look.
