/\ I have used 4-FA and methylone together... well, 4-FA followed by methylone 3 hours later. That was all right, I felt fine afterwards. MDMA and methylone together, however, made me about as miserable as I could possibly have been.

I had a tiny taste of MDPV this afternoon... trial no.4 or 5 altogether with this drug. 1-2mg smoked and then about 2 or 3 more later, under 5mg total.
Much more focus, and a mild moodlift, but also an astounding lack of euphoria, hence I don't expect any serious mood-comedown either. Found it to be fabulous at this level for some pattern programming on my drum machine. Sharp and clear, without me getting carried away on cloud 9... though music does sound a tad better. when it wore off I suddenly found the same music I had liked earlier to be a bit unnerving... in that respect MDPV is like all stimulants... including methylone. Except that the musical enhancement is much subtler and cognitive as much as appreciative, which is nice.
I can sense, though, that MDPV - like all stimulants I have ever used - would probably turn sour on me if I used it too regularly or if I kept redosing when I take it. But modest doses are really quite nice and no more stimulating than nootropics for me.
