PV-9
PV-9 (alpha-pyrrolidinooctiophenone) is a synthetic cathinone stimulant of the pyrrolidinophenone family, an eight-carbon chain homologue extending the PV-8/alpha-PVP series. It is a niche research chemical with essentially no published human pharmacology. Reported effects are anecdotal and describe a potent, long-lasting stimulant with heavy redose pressure.
01 Overview
PV-9 is an alpha-pyrrolidinophenone ('pyrro') cathinone sold as a 'research chemical'. It continues the chain-lengthening trend of the series; users report a potent, focused and long-lasting stimulant with strong compulsive redosing, though it is among the least-reported members of the family.
The class hazards apply in full and are amplified in the potent pyrrolidinophenones: compulsive redosing, cardiovascular strain, harsh comedown and unknown neurotoxicity. There are no controlled human studies, so figures are approximate and drawn from user reports.
02 Mechanism
Presumed potent inhibitor of dopamine and noradrenaline reuptake with little serotonergic action, typical of the alpha-pyrrolidinophenone cathinones.
