alpha-Pyrrolidinovalerophenone (also known as α-PVP, A-PVP, alpha-PVP, and Flakka) is a synthetic stimulant substance of the cathinone and pyrrolidine chemical classes. It produces medium-lived cathinone-like stimulation and disinhibition with a pronounced euphoric “rush” component when administered.
α-PVP is chemically similar to other pyrrolidine compounds such as MDPV and to other cathinone compounds found in the khat shrub of eastern Africa. It generally comes in the form of either a crystalline powder or crystallized shards which users can ingest to produce powerful but short-lived euphoric stimulant effects which are comparable to those of methamphetamine and cocaine when insufflated or vaporized.
α-PVP has been subject to much scrutiny by the media, similar to how MDPV and “bath salts” were portrayed in early 2011. Very little data exists about the pharmacological properties, metabolism, and toxicity of a-PVP and it has little history of human usage. It is commonly mass produced in China and commercially distributed as a research chemical by online vendors.
