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.

Effect Profile
Scores (1–10) curated from multiple sources:
- Effect keyword matching from PsychonautWiki catalog
- Weighted by importance: core (×3), major (×2), minor (×1)
Strong euphoria with moderate stimulation, mild sensory enhancement, low empathy
Strong euphoria, anxiety/jitters, and focus with mild stimulation
Tolerance
Tolerance Decay
Acute tolerance: develops within a single session — the reset numbers above apply after sustained heavy use, not after one binge. Within-session tachyphylaxis usually resets largely overnight.
