Research Profile of 4-FMA

4-FMA is the para-fluoro analog of methamphetamine and one of the most well-rounded releasing agents in the fluoroamphetamine series:

• Fast onset (15–40 min oral, 5–15 min insufflated)
• Duration 5–8 hours (oral), 4–6 hours (insufflated)
• Pronounced entactogenic warmth + strong stimulation + mild-moderate visuals
• Triple monoamine release (dopamine ≈ serotonin > norepinephrine)
• Significantly smoother body load and lower neurotoxicity profile than 4-FA
• Clear-headed euphoria with excellent music enhancement and empathy

Laboratories describe 4-FMA as “the perfect hybrid of MDMA and classic amphetamine – clean, colorful, and highly functional”.
