RCs α-PHiP Thread


Sep 2, 2013

  • 4-methyl-1-phenyl-2-(pyrrolidin-1-yl)pentan-1-one

Pulled from Wikipedia:

α-PHiP (also known as α-PiHP), is a stimulant drug of the cathinone class that has been sold online as a designer drug. It is a positional isomer of pyrovalerone, with the methyl group shifted from the 4-position of the aromatic ring to the 4-position of the acyl chain. In a classic 2006 study of pyrrolidinyl cathinone derivatives by Meltzer et al. at Organix, the alpha-isobutyl derivative of pyrovalerone, O-2494, was found to have the highest potency in vitro as an inhibitor of the dopamine transporter of the alpha substituted derivatives tested, however it was not until ten years later in July 2016 that α-PHiP was first identified as a designer drug, when it was reported to the EMCDDA by a forensic laboratory in Slovenia.

I tried it as a a-pvp a-php replacement. Extremly caustic impossible to vape, same for insuflation.
Down the drain, waste of health, time and money if you ask me.
Experimental comparisons with aPHP and hexen are positive. Less distracting than either, but similarly high urge to redose.
What stuff did u get ma

mate what did u get? Doesn't sound like pihp. .the stuff is best in a vape or smoked but warning it can be the devil as it's a constantly wanting u to redose to get that almighty high..orally first time and line will keep u going for hrs and if u want to redoese hit the vape
Sorry about that. Newbie here ..I've never tried the others that's y I'm keen for a chat with someone to detail the effects ects
it is a bit more softer than a-pvp or a-php but it is still very mania inducing, best to add a benzo..
Necrothreading, but just tried this for the first time about 20 minutes ago. Vaped a low dose in a glass pipe.

I was almost falling asleep before I vaped, now I'm wide awake and extremely alert. Little bit jittery, but that should level out soon. Feels pretty good. Will update if I notice anything further.
its a bit less potent than a-pvp or a-php but still pretty strong. also found it a little less reinforcing than the aforementioned...
I really disliked A-PHP, I imagine this drug to be much of the same. Maybe it was a bad batch or maybe I just don't agree with it very well, but no rush and no fun...
I felt a massive rush personally, for me it was almost like coke with legs. 20mg lasted a solid 4hrs
I'm tempted to give this one a try soon. I shouldn't but when has that ever stopped me.

Anyone had any luck using this one functionally?
Any feedback on alpha-PHiP (also known as alpha-PiHP)? It is an a-PHP analog.

How does it compare to a-PCYP?
