I'm just guessing but I heard 2ct2 is real visual and similiar to mescaline, 2c-e is also real visual, I'd say similiar to LSD if you're familiar with that stuff, and 2c-i I'm not too sure about but I hear there aren't many visual distortions but it's more of a stimulant and a good one for social occassions.
I wouldn't mind knowing how 2c-b, 2c-e, 2c-i, 2c-t-2/2c-t-7 compare. From what I've read, 2c-b is the most sensual (like mdma/lsd), 2c-e is the most visual, 2c-i is more like Mescaline/LSD, and 2c-t-2 is similar to 2c-t-7. Shuglin comments: "If all the phenethylamines were to be ranked as to their acceptability and their intrinsic richness, 2C-T-7 would be right up there near the top, along with 2C-T-2, 2C-B, mescaline and 2C-E."
2c-i is extremely happy stuff. I find the body sensations are better than MDMA, and it's an extremely euphoric, pleasing high. The visuals tend to lean more toward everything being cute and bright and appealing, but nothing terribly fantastic. I mixed it with a little DOC but that's a very speedy mix.
