Greetings. New member, registered to add my personal experience to this topic.
I have been vaping alpha for the last few weeks, in true weekend-warrior style. I use a flat spoon pyrex pipe, the type generally used as a modified hot-knife for smoking hash oil. I accomplish this in two ways:
1.) Heat the spoon and dump alpha onto it for an instant "hot shot".
2.) Moisten the accompanying rod (glass ball on end), dip it into alpha, and roll it around on the hot spoon for a more measured vape.
You cannot allow flame to come in direct contact with the alpha. It promptly destroys it, leaves behind a nasty residue and the resulting hit (tastes like shit) has next to no activity. You MUST allow it to melt and then come to a slow boil, while gently inhaling. This results in a very powerful means of administration with minimal loss of product. The taste this way is pleasant to me, reminiscent of auto anti-freeze in that it has a "sweet" or "aromatic" flavor with an almost gasoline-line after taste. I know that sounds bad, but to me it isn't.
I've never messed with MDPV - too much bad publicity. With a-PVP though, I can sleep within 4 hours of my final hit. I can also eat just fine, often devouring burgers between hits. The hard part is stopping while there is material left, but that's not news to anyone here. I have pushed things to the extreme (for me) and stayed awake nearly 36 hours on alpha. I saw the shadow peeps, said hi. Heard the voices and reminded them that I live in 'Merica and expected them to speak English. They did not deem to do so, so I ignored them. Seriously though, no real paranoia, absolutely no psychosis. Went to bed and woke up feeling a bit worn out, but nothing like a hangover. Never have noticed any major comedown.
I find it to be intensely pro-sexual, particularly with repeated administration. Oral admin was nothing worth mentioning. Never plugged, no lines. I was about to toss my first gram but decided to try the vape first. I, personally, am glad I did.
YMMV
