Sorry for putting this thread up again whereas last reply was year and quater ago, but I think this two RCs are popular nowadays (athough MXE can´t be legaly obtained from a lot of countries in Europe now) and few to many people got an idea to mix them..
From my experience, It didn´t feel toxic as all. 2 psychonauts (me and friend of mine, let´s call him Y) tried combo of MXE and aMT yesterday night and enjoyed it.
I had about 40 mg of aMT (oral and plugged), also drank a poppy tea from 5 pods (usually dose of pods from my source is about 8-10 with no tolerance) about 3 hours before trip andc also smoked a few bowels of pot. Y had 50 mg of aMT oral. Each of us consumed about 100 mg of MXE nasally during the night. We also drank a ginger tea for avoiding nausea during aMT comeup.
The comeup of aMT was quite speedy, Y couldn´t slow down to music we were listening, but I enjoyed music a lot. Especialy songs from Oasis or R.E.M.. After about T+3h into aMT we both dosed about 20 mg of MXE. After about twenty minutes strong wave of empathy hit us and we were unusual openly talking about past. At about T+4:30 we again dosed almost the same line as before. We both were like on speedy and more euphoric MXE trip, so we decidet to give a little walk in the night. Coordination was impaired, especialy in terrain with the lights out (and we have lights turn off most of the time). Y wants to dicover the world around so much that we both walked around 5 km before we came back to our place. We also walk extremely slow with lot of brakes to talks and Y also by his worlds could´t think and walk at the same time in the beggining :D
At T+8 we both insulffated about 50-60 mg of MXE and I also smoked a lot of pot, when MXE hit after a half an hour, I started to be tired a lot, speedy aftereffects of aMT start to substitude behind effect of pot and poppy pod sleepy phase. MXE also knocked me out that time, which is unusual for his chemical.
We both managed to sleep and we both slep instantly after about T+9:30. Last experience with aMT I coudln´t slept for 12 hours afterwards, so I was quite surpised.
Woke up after about 4 hours still feeling something. No hangover yet.
Altogether it was very enjoyable experience, I don´t want to guide someone to do this combo cause it is maybye quite dangerous (although we don´t know a lot about MXE anti-deppresant effects and if they are dengerous if combine with weak maoi such as aMT), but I also regulary drinked Passionflora tea to 4th day before experiment, wich is weak maoi too and I don´t experienced any sing of serotonin syndrome (my temperature was mildly high like with every aMT trip), just nice and mellow experience.
Still, doesn´t beat MXE + poppy pod + pot combo alone for me, although it´s potentionaly dangerous too, because of possibility of respiratory depression.
