ive never mixed the 2 myslef, but judging on effects profile, its probaly safe to assume that it is highly probable that the combo would cause a hell of a tachycardia, and both drugs could intensify each other's bad side effects. not to mention having to deal with double the crash at once! plus IMHO if you have mdpv, just do it solo! its WAAYYYYY better than mephedrone!!!!PeeVee blows meph out of the water, no doubt what so ever....for me atleast. the high is much cleaner, you dont need to worry about your nose clogging up unlike with mephedrone cuz instead of railing 100+ mg, you only need like 10mg w/ no tolerence(up the nose, which is btw the preffered ROA for this compound...ORAL seemed to cause freqent tachycardia when ever my body changes elevation quickly(e.i run up the stares, get up from laying down too quickly, or even just moving your head from a lower-to higher elevation quickly, or vice-versa...such undesired side-effects tends to induce paranoia) ....BUT also maybe these effects where only unleashed potentially becuase i waited too long into the comedown to redose(which ill explain more that later) ...but i mean, i was waiting for the oral to kick in after a long day up the nose...so wtf can i do?-besides having notes taken and a lession learned for next time

). So even if you had the biggest tolerence in the wolrd the amount needed is wayyyy less than meph, so thats good for your nose and your wallet!hahaha i dont want to sound like im advertising(seriously, sorry for raving about it in such a way that sounds advertise-y, cuz this is not my intentions, just the way i feel after having just recovered my nose from a little meph binge ....it was clogged for DAYS afterwords!!...so my current veiws are indeed somewhat prejudice/dislikeing towars mcat) but no-joking, from a non biased perspective the high is tremendously better(richer,deeper/more demensions/possible outcomes of euphoric feelings to it) , lasts longer and is way cheaper then meph! ,And i havent seem to find it makes your pupils big at all, the only way someone can tell your high is of how you wont shut the fuck up and stop moving around!!hahahah The euphoria is also EXTREME with PeeVee, and it makes you feel REALLY confident about whatever yout doing, and also at times can make you feel REALLY compasionate and empathetic to a level only comparable to mdma. so you draw the conclusion about what you should have, if you have the option of PV solo over meph/a meph combo with PV. The only thing i may try to warn anyone getting PV is to only, and thats ONLY(!!!!) to get it if you know for a fact that you have extreme self control, because if feels so amazing that you WILL want to redose it for the rest of the day/night untill you go to sleep. but the thing is, sense your redosing on a strong stimulant...you will never actually GET to sleep, so you must learn where to put the breaks on your PV marathon(cuz believe me, after you try it and feel it anything like i did...you will sponstaniously create a strong tendency to go on a marathon with it

my suggestion is(if i may have one:},would be to just DONT stay up for more than 2 days MAX!!! .PERIOD. than give it a break of like 4-7days. Its good to do that cuz for one, you wont be extremely sleep deprived(which alone makes me paranoid and delusional. ..in others words =Not Fun. especially when stimulants are added into the mix, which tends to escalate such things IME.), and for 2, you probaly wont be eating much, which while your high you dont notice how tired you really are, and which also will only add to the shitty-ness-level of the comedown thats ahead. and last but not least, 3, becuase the more this chemicals becomes part of your normal brain chemistry(e.i frequently redosing) the less you will feel its euphoric effects(which i believe is kind of a[seemingly accurate]rule of thumb for most drugs with initial euphoric effects)...and IMO those amazing-feel-good feelings are what its all about(apart from the unconvincable feelings and host of other confidence driven feelings, and even non-confidence related feelings that are just fucking phenominal! ...with PeeVee). and also after about +17hours of dosing redosing(starting at a late night, and redosing all through out the day) i seem to notice more psychedelic(very subtlely tho, more like being more sensitive to energies in a similar way when lightly tripping, but very UNlike tripping in any way,..if that makes sense) kind of effects, but i think sleep depravation largly contributed to this instead of the drug's unfeathered effects.
And also i feel like i should add something based soley on my own obervastions of how this drug might* work, but of which im not %100 sure on, so im Definitly NOT saying anything DEFINITIVE here, but if it is true, then it would be INDEED some important info that should be avalialbe to anyone who plans on hanging out with PeeVee for double-digit hours(or even just a few back-to-back doses) >>>and that is, -IF- my little theory is correct, ofcourse!*(im not a scientist or have a title to be making such claims, but it just something i thought u could point out to see if anyone one else has noticed the same things happening)>>>Which is NOT to wait too long into the comedown to redose, or else the high is different and losses its "magic" or so to speak(for me its the happy-go-lucky, loved up, euphoric, in-the-moment/undiscriblebly GOOOOOOOD(!!!) kind of effetcs)...Thats my little theory anyway(btw in no pharmacologist or scientist or have a title to be making such claims/constructing theories, its purely based on potentially-incidental obervastions) and it has yet to have been proven(; ....So the theory is[once more, and more spelled out,, for you slow and sleep riden-ed people out there] that because you waited too damn long into the comedown to redose(i would say about +20mins.), from that point on, the high is not nearly the same it was anymore. Not nearly as fun, euphoric, and happy-toned as what you where consistantly feeling when you where [relatively]quickly redosing earlier! its more of a depressed-toned buzz, something straight out of a comedown. (also highly likely that it has largely something to do with certain chemicals' deplition in your brain either theories are....UNproven, tho:[) .....so maybe, just maybe...if this theory is correct(out of MANY that are made regarding RC's)...That there is a 15-30min[?] relatively narrow window of time once the comedown hits, that you still have a chance to redose and feel the same way you felt beofre.. ...utterly AMAZING[!!!] , becuase they those same chemcials that made you feel that way are still present(in how ever minute amount...), and have a kind of "re-booting" effect when the same drug is administered again in time, before its completely deplitied from the brain, untill your brain naturally re-makes it agains(after however sufficient amount of time is needed without ingesting the drug again). So to all you pharmacologists out there, Tell me...Is this possible atleast? or am i just wayyy off base? Was this just a coincidence that the high just turned into a empty tachycardia-filled-depressing buzz the first second i waited for longer than ~~20mins(maybe even 10-15mins more than that)after intitial the initial comedown feelings took in, to redose? ....Or was it just some sort of un-aviodalbe chemical deplition that was taking place?[/B]
The high is SO dramaticly different, its almost like its a different drug, i guess(for w/e the cause being,)that this is the dark-side of the drug, and which is in my opinion is not even worth it to keep redosing after getting there(unless from that point on, your sole purpouse in using it is to stay the hell awake,...,but at the cost of paranoid highs and....idk,, stuff i wouldnt even consider "recreational"...ESPECIALLY compared to the potential Bright Side of it),
P.S:sorry for the loooong rant, but im sure you guy see where im coming from.
