After handling 1.25g of mdpv, there is easily 700-800mg left after 3 weeks. I have ethylphenidate, MPA, 3,4-CTMP and AMT (i need to dedicate a day/weekend to this!) and I prefer the MDPV.
I take it like my mate did, with a couple clonidine as MDPV really rattles the heart, and some benzos (etizolam) basically because I like smoking it, and 20mg losf is gone in 3 hours. lol.
That said, out of the 1.25 (unweighed just sold as that amount) some was given (a couple pts) to a friend, with a warning and a clonidine and seroquel to sleep. I couldnt honestly let anyone have more than 20mg of this and not have the clonidine for heart and seroquel to abort and sleep. If they have benzos , great even better.
I have not IV'ed (nor do i plan to to be honest... i have only ever IV'd meth, and methadone, and the latter was a mistake and the former was just like me eating 50mg and waiting 30min) this stuff but I heard from some junkies not on here that the rush is intense, although this person was talking about 100mg+ shots and saying that people would come to his house to buy and beg to get a shot his size, and they would end up dropping from it or in hospital).... Idiots (and an idiot drug dealer, who only knew that x amount is what he takes and that that could kill another person, and did kill people I think, murray bridge soth australia had mdpv deaths and i think because people treated or sold it in points.
I met someone who claimed he imported kilos of it from china (and still did, in jail,) and he was telling me people were paying $70 per point of mdpv down in murray bridge. Craaaazy. Some people must like it more than meth.
Personallly I hate the cardiac stimulation more, its got a weird (nice

) taste to it. but It's still just me adicted to the act of smoking something in a glass pipe. I cant see it being a good route of administration.
My experience with stims is: 6/5APB (awesome), ritalin, meth, dextro amphet pharm5mg tabs, MDPV, MDMA, MDA (possibly in a pill i had), and my concurrent use of ethylphenidate/mdpv/mpa that i have access to now. So out of them all, obviously I like MDMA and 5-6APB the most, and MDA, then meth, MDPV, dextro-amphet pills 5mg, then ritalin last...
Out of all of these, 2-3 days awake on MDPV and I was hearing real full on voices, never ever had that sort of psychosis before. EVER, and i was a meth head. No visuals, but I did then realise that it was time to get off it and take benzos/clonidine/seroquel and a bit of methadone on top to sleep.
Scary drug for prolonged use. Use it for a night and the folllowing day to stay up, its ok just watch the redosing and heartrate, I wouldnt advise co administering stimulants with downers like I do, but I am aware of the risks and know what my meds do, I am also on methadone also so my doses will be higher until respitory and heart rate is higher due to being depressed already.
