To expand a little bit on the naming conventions and the order things were synthesized in that Xorkoth was talking about, it's really sort of a "yes and no" answer as to whether or not TMA-2 is a DOx molecule, because it's basically that it specifically isn't by name, specifically because it is actually the granddaddy of all DOx molecules. Alexander Shulgin loved mescaline so the amphetamine version, TMA, with the 3,4,5 pattern like mescaline itself was one of his first ideas, and when it turned out to be successful enough one of his next ideas was to try rearranging the three methoxy groups all around the ring which became the TMA-x group, with TMA-2 being the 2,4,5 pattern, and since TMA-2 was the most active and notable of the TMA-x group according to him, he decided to come up with ideas to alter it further from there, one of which was removing the oxygen from the methoxy group on the 4-position so that it was just a 4-methyl instead of a 4-methoxy, which would be named DesOxyMethyl, or DOM, which is to say, the name DOM literally means "TMA-2 with the 4-methoxy replaced with 4-methyl" and the DOx group naming convention in general is derived from DOM switching out the M with whatever letter represents what is in the 4-position instead, so essentially TMA-2 cannot be a DOx because a DOx molecule's name is literally defined by what makes it different from TMA-2, but that is done because TMA-2 is itself the first psychedelic molecule discovered that has the exact same type of molecular pattern as the DOx molecules and therefore it is the prototypical reference of all DOx molecules, and is just as much meaningfully within the same group as the rest of them are.
Incidentally, I love TMA-2.

We've now taken it three times at 25, 35, and 45 mg, and every experience was distinct and memorable. It's given me a challenging psychedelic emotional headspace comparable to 2C-E, hallucinations comparable to DOB, an empathogenic and stimulating high comparable to MDMA, and some of its heavier visionary effects I can only really more readily compare to indoles like LSD and MPT so far, not to mention the fact that I got briefly out-of-body with an entity interaction while meditating in the later hours of the first time we took it. The last time I attempted to take inventory I decided that it was probably at least one of my tied top favorite phenethyalmines so far, along with 2C-E, though three times is still pretty early into our relationship with it of course. The last time we took it I was slightly put off by the fact that it seemed to make me irritable in conversation, but I think this is more of a problem I'm having and trying to work through with more stimulating drugs in general right now more so than it is a problem with TMA-2 specifically. I spent the rest of the trip obsessively analyzing the behavior because it was like that.... The internal visions were so concrete and corresponding to my thought process about it all that it took me a good while to consider it consciously enough to realize that it wasn't just me using my imagination really, really, really vividly. I very much look forward to using it again, though probably not for a while.
