I've had 250mg sitting around for about 6 months, I acquired it for use as a study aid. Here's a quick experience report. Method of ingestion was insufflation.
Low Doses:
Typically, during finals I use methylphenidate. I felt like trying something new because the crash is so horrible. With small doses of MDPV I experienced no euphoria, only a slight sense of speed and no crash or comedown whatsoever. Because the "sense of speed" was very slight and didn't last more than a couple hours, I assumed I didn't take enough and gave up on pulling an allnighter to study. Except I couldn't sleep. Even on a very low dose (no reup) I was up all night. Even if you think its gone, it probably isn't. Its very "clear" on low doses. There is an urge to redose... very strange considering all other effects were very mild.
Oh, one really important point is that MDPV does not give you the "one track mind" or enhanced concentration that methylphenidate does, and is therefore not as useful in studying.
Used it maybe 3 or 4 more times during that semester, for finals and papers. It never really occured to me to use it as anything more than a study aid, since I'm really no fan of stims. I've tried methamphetamine, dextroamphetamine, various appetite suppressants and I'm a cocaine and methylphenidate veteran. Opiates will always be my kryptonite, stims usually don't do it for me.
High Doses:
Last weekend... finals again. Used a bit of MDPV, studied, took the exam next morning and owned it. I felt like celebrating so I decided to give in and redose. 48hr binge ensues. Slept for 6hrs, woke up and dosed. And again.... and again.... until I just woke up. It's Wednesday evening. I finally passed out sometime around 8am Wednesday. Over the course of 4 days a 250mg baggie became just under a 100mg baggie (Note: A portion of that should be attributed the first 4-5 experiences at lower doses, however).
There is an immediate sense of euphoria. Enjoy it, because it only lasts MINUTES and it is the only period of time on this substance that you will not have the urge to redose. Very speedy. A sense of well being, and speediness, ensues... maybe until T+ 1 hour, at the most. During that phase you will get the urge to reup. Then you begin to enter the "clear" period of the high I described earlier. This is when your urge to reup will be highest. If you plan on sleeping that night, never redose... as you are still very much under the influence of MDPV... it just won't be evident until you try to sleep.
Interestingly, I never experienced a crash or comedown of ANY kind, even after consecutive 48hr binges. I was, however, able to successfully use a couple bowls of budder to pop myself out of the binge and get to sleep surprisingly quick. Very high potency marijuana, or in my case a couple hits of budder (~99% THC), seems to work very well in helping me control my urge to redose and actually puts me to sleep very quick. I prefer the budder extract because it only takes an amount the size of a pinhead, meaning I can smoke indoors without bothering the neighbours.
Conclusion:
Pros:
- Great social lubricant
- You will fuck until your genitals bleed.... literally.
Cons:
- At least as addictive as cocaine, with similar shortcoming of a really short period of euphoria. Not as addictive as junk, IMHO. If you have self control you will be fine.
- Temporary side effects: Binging brought with it slight paranoia and pretty bad lethargy. Also, it does strange stuff like making me jump at the sound of a dripping tap, or being startled by the sudden thought that a parked car was actually driving towards me.
- Possible permanent side effects??? My fucking tongue & teeth have minds of their own all of a sudden.
So I'll definitely be keeping some around. I'm meeting up with an old fling next month, and I'm looking forward to banging her until she bleeds.
MDPV does deserve respect. But
nanobrain is hyping it up worse than some Fox News story, as if he's some kind of drug war propagandist. At this moment, I have no urge to touch the ~100mg baggie in my freezer. I got it out of my system. If you can use cocaine, meth, and strong opiates on occasion without forming a habit.... you will be fine. Self control, guys. Take some personal responsibility for your lives.
I would really like to hear from nuke about the jaw tremor. Has it gone away or is this just one more stupid thing I'll have to live with? Sometime during the second 48hr binge, I developed the strong urge to "chew". Like some kind of cow. 8) My tongue swirls around in my mouth, licking my bottom teeth and roof of my mouth uncontrollably. I actually licked my tongue raw... I thought I would be fine when I woke up. I'm still fucking doing it! It worried me to the point that I started on some research which led me here.
Hope my experiences help someone!
