α-Pyrrolidinoisohexanophenone (mainly known as A-PHiP or α-PiHP) is a stimulant drug of the cathinone class that has been sold online as a designer drug. It is an 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. A-PHiP acts as a selective dopamine reuptake inhibitor. Unlike other alphas, which also act clearly on norepinephrine and are not so selective, alpha-pihp shows a very high selectivity for dopamine and has a stronger effect on dopamine. It has very little or no effect on serotonin and norepinephrine. It practically only affects dopamine receptors and inhibits almost only dopamine.

AN USER EXPERIENCE ABOUT a-PHiP:
"... It was our first time vaporizing and… smoking crystals off a tin foil felt like a very crackhead move in itself. Especially considering the fact we were doing this hidden behind a car, on top of a hill above this lil village.
