I see a lot of reports and comments about 2c-t-21 and how it seems more, emotional, open, social, easy to communicate on, etc. Also I remember being goofy, making jokes sort of out of nowhere that would make people crack up (more joking than sober i guess, just in a more humorous mood).
I also see people talk about 2c-i being more open, emotional, than a lot of the others. Also it seems like people sometimes experience a 'hangover' of some kind, someone described a mild depressed feeling similar to MDMA days after 2c-t-21, also 2c-i seems to do a similar thing to some people sometimes (or leave an 'afterglow').
I think these two have something in common (well, i mean they all do), i'm 'guessing' some kind of serotonin release, just because I find mixing gabapentin (neurontin) with either of these brings a lot of euphoria similar to mdma. Not just the euphoric feeling but the openness, emphathy towards others, etc. This doesn't happen with 2c-e (that effect from gabapentin), and 2c-e seems real 'clean' and no forced mood lift either, and I dont remember people talking about hangover's with that one.
I have tried 2c-c and 2c-d, which are great, but i notice there is no real after effects and I used to think 2c-i was clean, sure it is but after trying some others, I try 2c-i and it seems...ahh..blah.. something about it. Some day I will mix neurontin with these and see if that thing happens, i am 'guessing' it won't just because those don't seem to have the mood change/openness like (or as much?) as 2c-i/2c-t-21. I've posted about the "mix" before but I do not think anyone on here has tried it or I would have seen posts - so maybe its a good idea to uhh, not try it! bad bad bad!
