    Summary dose.wiki TripSit PsychonautWiki

    3-FMA is a research chemical stimulant with entactogenic properties, characterized as a serotonin-dominant triple monoamine releaser. It produces effects lying between functional stimulation (like 2-FMA) and euphoric entactogenesis (like 4-FMA). The substance has an extremely short history of human use and unknown long-term toxicity profile.
