Neither me or the girlfriend suffer pupil dilation on mdpv...not at all, do on other things though, Mephedrone and the like and so on, girlfriends pupils are HUGE on mephedrone, mine tend to be about double normal size, so not that big really, can almost pass for normal.
Have just bought a G of mdpv, first batch was almost 3 months ago...lasts us ages, neither of us have any problems whatsoever with fiending, thank god.
Have read many replies with people claiming the stuff is getting cut to fuck now, I did wonder when I paid for it if I'd find the same.
Bought from the same vendor as before, diluted it in vodka (not interested in snorting it, seems to be too much risk of fiending done that method to me) so that 1ml of liquid = 2mg of peevee, took normal amount (4ml=8mg) and low and behold it is EXACTLY the same as the first batch....sorted.
Having experimented I know how much I need to take to get a nice effect, just a little too much and I'm edgy and twitchy with a noticeable comedown, just enough and it's lush, I know what I'm looking for and there is just about no comedown either...and curiously my tolerance is no different now to what it was 3 months ago...
I think perhaps some people try this stuff and expect to get as fucked off their tits as they do on other stuff...that just isn't the case...at least with me and me woman anyway!
