Arrrghhhhhhhhhhhhhhhh....
I hereby retract what I said on the 'white' MDPV from an ostensibly well-known UK chem source, a small amt. of which I recently acquired for research purposes.... if it's MDPV, it's crap. Definitely has a stimulant effect, somewhat moreish like MDPV, but from there the resemblances seem to go downhill.
Seems to require a higher dose that usual for decent effects (close to "panicky" levels, which is not fun) and larger amounts too. Pretty well crap sex-wise (so far anyway, as per "one orgasm the last 14 hours straight of use"). Causes somewhat dilated pupils and a more rapid heartrate than I remember. Not much euphoria. Basically just sucks overall compared to (memories of) tan MDPV.
I could be wrong and this is MDPV, and I'm reacting to it differently than usual -- it's been over a year since I last used it and am on different prescribed meds (Effexor XR, which shouldn't interfere). Actually, I won't claim that it *isn't* MDPV, only that it seems like 30% to 50% "there" compared to decent MDPV experiences I remember. It's possible (tho not likely) it's awesome shit & I just need to get familiarized again with MDPV's dosing/frequency peculiarities.
Whatever it is is fine for what it is... acceptable, OK, fair, decent, workable, so-so, better than nothing, not bad, etc... just not very good either. You'll sit there as usual & attentively/repeatedly do nothing worthwhile (and forget you're doing it for hours). You'll still get stiff/sore & anxious, forget to eat/sh*t/piss (& have trouble going when ya do), sweat will still run into your eyes & burn like f*ck, your pits/privates will still smell like hell, your neck and lower back will still ache... all those "goodies" ya get from stims
are available from this stuff 8(

. Enjoy... Pssssssshhhhhhhhht.
P.S. seems there IS a pyrrolidine odor about the stuff at times, so it probably contains MDPV... that's all I can say.
