What is 4-FMA?
4-FMA (4-Fluoromethamphetamine) is the para-fluoro analog of methamphetamine, renowned for its unique balance of potent dopamine/norepinephrine release with significant serotonin activity — creating the most “entactogenic” profile among fluorinated amphetamines. Far superior in warmth and duration to its 2-FMA or 3-FMA cousins.
- IUPAC: (RS)-1-(4-Fluorophenyl)-N-methylpropan-2-amine hydrochloride
- Strength per pellet: exactly 150.0 mg active base equivalent
CAS Number
1354631-28-6 (hydrochloride salt – supplied form, though often associated; confirm via CoA)
