Description

4′-Methyl-α-pyrrolidinopropiophenone (4-MePPP, MPPP or MαPPP) is a stimulant drug and substituted cathinone. It is structurally very similar to α-PPP, with only one added methyl group in the para position on the phenyl ring. 4-MePPP was sold in Germany as a designer drug in the late 1990s and early 2000s,^[2][3][4] along with a number of other pyrrolidinophenone derivatives.^[5][6] Although it has never achieved the same international popularity as its better-known relations α-PPP and MDPV, 4-MePPP is still sometimes found as an ingredient of grey-market “bath salt” blends^[7] such as “NRG-3”.^[7]
