^ Although I have to say,
After literally a year straight of pretty much week on week off use (on average) of exclusively dosing via IV, this has got to be the most physically benign stimulant you could consume that way (out of the big boys, at least). If I had done that with meth, I seriously think I would've lost an arm or something by now, not to mention fried my brain into a vegetable. Now that I've been clean from it for about a month, my arms are basically scot-free other than two VERY light scares at my highest usage points – the elbows.
Not recommending anyone pick up an IV stimulant habit by any-means, but if you're gonna go down that road anyways, MDPV has got to be the least terrible stim you could pick.
Thats what I thought I'd do before I got into it, but it turns out

D) IV'ing has an unbeatable rush (many people don't seem to enjoy it over smoking, I sure as hell do). It feels 'cleaner', yet stronger, to me..
