I liked the 2C-T-2 but I didn't love it like I did 2C-T-7. Also I got GI issues for quite some time, including two unusually painful dryheaving sessions. A buddy recommended a warm shower and that helped a lot. I had the strongest CEV imagery there, it was really unique. Very detailed fractalized images mixed with hallucinations of flowing quicksilver type textures and memories of intercourse with women in the past.
After my first attempt at throwing up (my stomach was empty - a banana had probably already moved on), I got a sudden rise in effects which is kind of typical I guess. Everything looked very warm, colorful, and bold. There was some writhing on the couch as well. After I had that shower, I applied some body milk since it was my third shower of the day - I had had a martial arts training session in the morning which also seemed like a perfect preparation body energy wise. The skin sensations were kind of weird, but actually really liked being so aware of my physique. For me it was pretty recreational, I did not feel like I had to do therapeutic work on myself... perhaps because I feel very good about my life now, and am used to feelings of openness and peace.
It was a good day to be alive, that is for sure. I might try 2C-T-4 but unless I simply don't have the time for it, will probably go for 2C-T-7 again in the future, if choosing from any of the 2C-T's. 2C-T-21 doesn't really count as a normally versatile psychedelic in my book though it may be good for other things. I was not that impressed with it, but who knows it could be an enhancer or nootropic-like for some activities or situations. A downside of 2C-T-7 by the way seems the unpredictable dose-response relationship... but IMO all downsides of 2C-T-7 are more than worth it.
