Belonging to the ketone and pyrrolidine chemical classes, α-Pyrrolidinopentiophenone (a-PVP), also called Alpha-PVP, is a potent psychoactive substance and stimulant consumed for euphoria and used for forensic and research purposes. It was first synthesized and developed in the 1960s, with its potency level compared to a quarter of that of MDVP.
Also known for its IUPAC (RS)-1-phenyl-2-(1-pyrrolidinyl)-1-pentanone, a-PVP is a ketone analog of another compound, prolintane that has similar chemical structure and action mechanism to MDPV making α-Pyrrolidinopentiophenone a popular alternative to MDPV because both produced similar effects using test subjects, which have achieved stimulation, euphoria and increased focus/concentration.
This compound has a CAS# 5485-65-4, purity ≥98% when sold, molecular formula C15H21NO [C15H21NO.HCl (hydrochloride)] and molecular weight 267.8 and often appears to be a yellowish, white or tan powder in small white crystals. According to RC-Chemical, α-Pyrrolidinopentiophenone is closely similar but less potent than cocaine, quickly dissolves under the tongue and should not be consumed to more than one dose within an hour. Its euphoric effect comes in slowly, in about half an hour.
Following an oral ROA, a user might feel a slight increase in blood pressure, without any desire of drinking water, while feeling numbness under his tongue. Duration may last up to three hours, without any desire of re-dosing. When insufflated, a user may be able to experience euphoria for a longer time, although some consumers reported of experiencing effects slowly when insufflation is used.
But for others, they feel it working immediately after it enters their nose and so they achieve euphoria almost instantly within 10 minutes. In general, blackouts could be felt wherein a user can feel sleepy in an hour.
‘Mazzy’ of Official Benzo Fury said that it was a fantastic compound but newbie researchers should start with low dose because it could be overwhelming. He also said that it brought him energy, euphoria and sexual arousal, noting only a little of it went a long way so it is good value for money, too.
