2-FMA and a-PVP. Potencysand half-lives?

[swimming.since.99]

What is the potency and half-life of 2-fluoro-methamphetamine? I hear it is around the same potency as dextroamphetamine, however it is much more smooth, longer onset of action and has very long half life. A very powerful, yet clear and functional stimulant.
Do any of you guys have any real facts?

What is the potency and half-life of a-PVP? I hear it is a pretty potent NDRI with a fast onset of action and a moderate-long half-life, and of course a harsh comedown.
So what about this one? Do any of you guys have some real I fo regarding this stim?

Any decent info is highly appreciated

2-F-methamphetamine should basically have the same pharmacology as "normal" racemic methamphetamine. So go easy on it...

as for aPVP... come on now, can you not find anything in the literature or on BL? I think dosages are around that of MDPV, so 5-50mg ideally, but... who knows? Stimulant tolerance varies a lot.

IIRC aPVP lasts 2-3 hours.
