2c sysnthetic are all RC drugs i've done 2c-i and 2c-e, 2c-i produces none to mild visuals and a small stimulant effect very much like a strong dose of good speed, 2c-e gives all that x5 so you'll get alot more visuals, which will be more profound and bizzare and you'll get a more mind/body fuck from 2c-e and 2c-e is safer since it doesnt contain iodine. I loved 2c-e and didnt like 2c-i.
