Summary
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. Based on related compounds, potential neurotoxic and cardiotoxic properties are suspected. Use extreme caution with dosing and avoid redosing to minimize risks.
