    Summary TheDrug.Wiki

    Ξ±-PPP is the three-carbon homologue in the pyrrolidinophenone series (shorter alkyl chain than Ξ±-PVP and Ξ±-PBP). It acts as a potent DAT and NET inhibitor with negligible SERT activity, but uniquely also functions as a partial norepinephrine releasing agent and 5-HT2A antagonistβ€”properties not shared by Ξ±-PVP. This 5-HT2A antagonism may contribute to its reportedly lower euphoria and reduced popularity compared to Ξ±-PVP.
