α-Pyrrolidinobutiophenone (α-PBP) is a stimulant compound developed in the 1960s[2] which has been reported as a novel designer drug. It can be thought of as the homologue lying between the two better known drugs α-PPP and α-PVP.


In the United States, it is a Schedule I controlled substance.[3]

Sweden's public health agency suggested to classify α-PBP as hazardous substance on November 10, 2014.[4]

As of October 2015 α-PBP is a controlled substance in China.[5]
