Although 2C-T-2 is obviously not the same, I thought posting this experience could be insightful:
I've insufflated 5mgs of 2C-T-2 about 1.5 hours after taking MDMA. I couldn't tell you how much MDMA was in the pill, though, but it was definantly a decent dose without any adulterants. Not exceptional, but more than enough to roll.
It was by far one of the most intense experiences I've ever had. I can't really remember coming up on the 2C-T-2. Although it effects you within 5 minutes of insufflating, it still takes about an hour before you reach the peak. All I know is that I was confused and content to just sit there letting my mind wander into space. I also thinking it greatly amplified the effects of the MDMA while also giving me a unique experience I couldn't get with either drug on it's own. It seemed as if there was some sort of synergy going on. But I can definantly remember everything once I peaked on the 2C-T-2. I was rolling as hard as I would have during the beginning of a peak on 3-4 doses of MDMA. And at the same time I was having some of the strongest hallucinations I'd ever seen. The 2C-T-2 was definantly affecting my thought processes, but my head was still fairly clear (amazingly clear considering how overloaded my senses were and that everything looked and felt like I was in another universe). Infact, while the effects of the MDMA were still amplified and I probably should have been really out of it, it seemed like the 2C-T-2 gave the experience a more serious and aware tone. After about 4.5 hours of taking the MDMA, the effects of it quickly began to evaporate. And as the effects of the MDMA wore off, the effects of the 2C-T-2 increased. After that it was like a very pleasant 2C-T-2 trip. Suprisingly, I actually had less of a body load than usual from the 2C-T-2. The visual hallucinations quickly got so intense that I could almost not even tell where I was or what I was looking at. The auditory hallucinations also got really strong at this point and I couldn't recognize songs I'd heard dozens of times. And the trip just stayed the same after this for another hour and a half before I took some Seroquel to knock myself out. It had definantly plateaued at this point and I would assume I would have started coming down shortly after anyways. The only other thing I really can't remember about this experience is how I felt the next day, but I'm assuming it wasn't good because I never had the desire to use 2C-T-2 again and I've only taken MDMA one more time since then, which was about 2.5 years later.
