Shambles did mention finding the Viagra + Stim combo uncomfortable on a number of occasions and with a variety of stims. Others seem to find it goes fine. There's an ADD thread discussing the potential dangers associated with combining vasodilators with constrictors if you go a-looking for it. It's mostly specific to mephedrone but it's the intrinsic iffiness of combined dilators and constrictors I'd be more worried about. But, again, it's likely to be a mostly personal thing. But it didn't feel at all pleasant or safe most times I tried Viagra for any reason on stims. A single aspirin and plenty of hydration (within reason) seemed to help me most without any dodgy-feeling stuff afoot but sure that's not ideal either.
I have no sources to hand to back up what I just said but, at the risk of slight hypocrisy, do you have any to back up any of that? Psychedelic amphetamines and "some sort of toxic cleaner" can be made randomly simply by combining MDPV with water? Really? Am no chemist but that sounds even less feasible than the actual Stuffmongerisation Process itself. Linky? Sounds impossible but will be trying the technique soon so would be good to read up on
"some sort of toxic cleaner" - While trying to look up each molecular build that could be reached after passing mdpv through water, one of the builds had several different possible chemicals it might be including some sort of toxic cleanser - there wasn't even a confirmation of which chemical definately fit that particular build. Others had no information. That is what I meant by it could not be confirmed (the cleaner that is).
Try searching for every possible chemical that C16H21NO3 could turn into (it's a bit tricky, because not all chemicals in the range are known, or are not listed anywhere online) when passed through water. The chemicals can go down by as much as 3.
It's not simply mixing MDPV with water - there has to be something else in there as well. There are numerous places where information on hydrophilic chemicals are available. If I could give a resource as to the exact chemicals MDPV could turn into, I wouldn't have needed to run the tests myself (not that it wasn't fun)
Basically, a hydrophilic chemical is passed through water, that said chemical will share some of it's atoms with other molecules in the water if they can take them. If one simply took mdpv and put it in water, then there would be nothing for the mdpv to share it's atoms with, and therefore it would remain mdpv.
Looking up mdpv chemical details (again, pretty much anywhere) will explain that it is hydrophilic.
And if you run through a quick look up of the possible combinations in its range (mdpv is C16H21NO3), you will see things such as PPP, MPPP, alpha-PPP, and a few others. I can't confirm that every one of them is possible to create that is within that range, but I can confirm that I've got some packaged up now.
I may not have the details at 100% but the chemical nature of MDPV is not hard to find, nor is information on hydrophilic chemicals.
And I would definately not suggest attempting the procedure. I felt like a real idiot when I overlooked mdpv being hydrophlic. If I had known that from the start, I would have skipped the tests all together. The point is it would be really easy to get quite a few unexpected results.
Edit: When I ran through the experiment myself, I honestly expected no change to the chemical, or at best a slight improvement due to the change from C16H21NO3- to C16H21NO3+ due to the added electron provided by oxidizing the base for stability. Just to be at least moderately safe, only small amount was tested. You cannot imagine the shock when I realized that the chemical was definately not what I thought it was going to be.
