What is a good RC to start with?

I have been reading a lot about the different psychadelic tryptamines and phenethylamines and am going to start experimenting once i can find a legit vendor. What is a good research chem to start out with? Also, any other information that seems prevalent is greatly appreciated.

There's a thread about this very subject already, and on the first page no less. Observe the first post in that thread specifically, and come back. Try and reformulate your question with what you've learned.
