    Summary TheDrug.Wiki TripSit PsychonautWiki

    3-FPM is a functional stimulant related to phenmetrazine, producing effects similar to amphetamine with reportedly less nervousness and euphoria. Users describe it as more subtle and focused, making it suitable as a study aid. However, significant concerns exist: some users report serious flu-like symptoms on comedown (muscle aches, fever, chills) potentially due to systemic inflammation, and rare cases of severe adverse reactions including vasculitis have been documented.
