Yikes! I was under the impression that 2c-t-2 may have MAOI properties a la 2-c-t-7. If this is correct, it may be a potentially dangerous combo. That said, I and quite a few others mixed MDMA with 2c-t-2 (over a decade ago before there was much talk about potential MAOI effects). It was an intense experience for all involved, with some experiencing quite a rough ride, others enjoying it thoroughly (when not holding on in a maelstrom of visuals). I would think a combo with MDA would be even stronger. Perhaps someone can comment more on the "safety" aspect.
