I read one report that alleged it may be cut with caffeine, but it is all hearsay at this point. My guess it is leftover from the last batch that was a 70:30 MXE to caffeine ratio. If it was actually a new synth I imagine there would be more availability and reports. I'll be honest, I felt a bit of nostalgia recently for the days when legit MXE was available. For now it is still a memory. There is a rumor that at least one lab in India is working on it. Again, just rumor which I am sure most of us are tired of, given the one year anniversary of its disappearance and countless rumors that never materialized since then.
