YMMV, as always. Shulgin's tastes are far from universal. Most people seem to prefer -t-7 to -t-2, and Shulgin himself indicates that -7 produces less bodyload with the only seemingly negative comment being that it lasts longer. Shulgin is a hero of mine, but in no way should his subjective experiences be taken as some authoritative guide to the value of different compounds. On a related note, he seems wildly inconsistent about how he feels regarding the length of activity of a compound. Here, he seems to suggest longer is a downside and further comments on the excessive length of one of the 'tweetio' analogs, but in at least one other place I recall him going off on a bit of a rant about how the obsession with shorter lasting psychedelics says something negative about our culture, that people feel they can't set aside the time for a full day of deep introspection and need a fast food, on demand kind of alternative. Then again, when discussing that 4-substituted tryptamine that lasts 2-3 hours but is otherwise similar to psilocin (4-ho-mipt or -dipt i think?), he also commented that a short lasting psychedelic will likely prove important if psychedelics are to make a resurgence in clinical psychotherapy as the risks of giving a neurotic or psychotic individual psychedelics would seem more acceptable if a potential bad experience would at least be over fairly quickly.
If *all* you got was sweaty and anxious, one of two things is probably true:
1. What you took was not actually a 25mg dose of 2c-t-2, or
2. For whatever reason, your body does not react in the usual way to this compound.
25mg is a fairly high dose and most people would experience a pretty strong +3 from it. If you just meant it was nothing special compared to other 2Cs or something then maybe it's just not the best one for you, but if you got literally no effects beyond sweating and feeling anxious it's possible you got a much lower dose than you thought or a dose of something else entirely, or maybe just inert powder... Or, as I said, that you just have an atypical response to this particular compound.
