'''MFPVP''' ('''3-Methyl-4-fluoro-α-pyrrolidinovalerophenone''') is a psychoactive agent from the substituted cathinone family, with stimulant effects. It was first identified in Sweden in April 2020 and was among the most widely encountered substituted cathinone derivatives in 2021, though it since appears to have declined in prevalence.<ref>{{cite book | url = https://www.emcdda.europa.eu/system/files/publications/13464/20205648_TD0320796ENN_PDF_rev.pdf | title = New psychoactive substances: global markets, glocal threats and the COVID-19 pandemic.
