I have a batch of white PV from a *snip* vendor, and it's very good IMO. Haven't had a huge problem redosing, although there has been a bit of fiending. Mostly I just fiend for more because I do a line, then just feel super clear headed and think I need more. Then a half hour or so later I realize I'm speeding like fuck and I'm gonna have a hell of a bad comedown. Can't do this stuff for more than a few days personally. It's just too physically taxing.
I am very curious about this whole beige/white/tan stuff, though. Have we figured out for sure what the differences are, or which batch came from where/when? Do you think the white stuff going around right now is legitimate PV? Its effects seem to match the descriptions you guys have given, and don't resemble what I heard of the older white batches.
