2-Fluoromethamphetamine (2-FMA) is a phenethylamine and amphetamine that’s been used since around 2012. It’s a research chemical and little formal knowledge about the substance is available.
It’s been described as an alternative to amphetamine and lisdexamfetamine, albeit with a lower recreational potential. 2-FMA primarily offers productive rather than recreational effects. Most users describe it as less inherently recreational than amphetamine.https://www.kyivpharma.com/product/2-fluromethamphetamine
2-FMA = 2-Fluoromethamphetamine
Molecular formula: C10H14FN
Molecular weight: 167.227 g/mol
Light: 10 – 20 mg
Common: 20 – 40 mg
Strong: 40 – 50 mg
Most people find there’s little reason to go beyond 40-50 mg. After that point, the stimulation may increase and the duration could be somewhat extended, but the chance of negative effects increases.
Total: 5 – 8 hours
Onset: 00:30 – 01:00
Most of the core effects tend to decline within 5-6 hours, but wakefulness can persist for 8-10 hours. Strong+ doses can extend the effects to some degree.https://en.wikipedia.org/wiki/2-Fluoroamphetamine
2-Fluoromethamphetamine (2-FMA) is a phenethylamine and amphetamine
2-Fluoroamphetamine (2-FA) is a stimulant drug from the amphetamine family which has been sold as a designer drug. 2-Fluoroamphetamine differs from 3- and 4-fluoroamphetamine in the position of the fluorine atom on the aromatic ring, making them positional isomers of one another. The replacement of a hydrogen atom with a fluorine atom in certain compounds to facilitate passage through the blood–brain barrier, as is desirable in central nervous system pharmaceutical agents, is a common practice due to the corresponding increase in lipophilicity granted by the substitute
