2CI has been said to be the most visual of the three, with coloring and visual patterns similar to 2CB but with less body load; 2C-T-2 is said to be less visual than 2C-I, with less body load than 2C-T-7; 2C-E would probably be the trippiest of the three.
I have tried 2C-B, and it was very visually interesting: closed and open-eye visuals, but much much too emotional for my taste.
2C-T-2:
Erowid Online Books : "PIHKAL" - #40 2C-T-2
2C-I:
Erowid Online Books : "PIHKAL" - #33 2C-I
2C-E:
Erowid Online Books : "PIHKAL" - #24 2C-E
Hope this helps. If you want to try something like MDMA, try "MethylOne", also synthesized by Dr. Shulgin. Said to have less of a body load and crash than MDMA, but I haven't tried it yet.
please PM me your link to your chemical provider. I am looking for one that provides 2C-E. Much appreciated. Thanks!
