It's definitely the most similar compound to MXE I've found. And, it doesn't hit the sweet spot in so many ways. It's sterile, clean, a bit harsh and metallic, and generally just doesn't have the magic that MXE has - the psychedelia where everything is full of magic and wonder. After effects were a bitch too. Oh, and it's super stimulating and the hole seemed to not last long at all. I plugged a decent amount, holed relatively hard, and then as soon as I was really into it, it started letting up and in my mind, seemingly demanding more to get back there, because I wasn't done yet.
Definitely don't combine it with LSD either, the stimulation is over the fucking top, and clarity of mind goes out the window.
It's ok but not great.
So it is pretty certain, that the magic of MXE comes from the 3-MeO chain. 3-MeO-PCE for me is "magic" pure, but it gets overstimulating and a little bit psychotic if you take too much. 2-oxo-PCE is clinical and causes an overwhelming amount of physical restlessness and mania the next day.
2-Oxo is great in combo with low-dosed psychedelics, though. Taken solo it causes long-lasting holes for me though (2h as far as I remember).
