4-Fluoroamphetamine ( 4-fa )
4-Fluoroamphetamine buy 4-FMA , 4-Fluoromethamphetamine (abbreviated 4-FMA) is a synthetic substituted amphetamine with stimulant, entactogenic and purported nootropic effects. Many users describe it subjectively as displaying properties and effects somewhere in spectrum between 4-FA and 2-FMA, but with subtle variations in its pharmacodynamics, kinetics and side effect profile that make it less desirable than either.
4FMA is rarely found on the street and is usually sold as a rare grey area research chemical through online vendors, occasionally along with related designer stimulants such as 2-fluoroamphetamine (2-FA), 3-fluoroamphetamine (3-FA) and 4-fluoroamphetamine buy (4-FA). Of these, it is one of the least potent and popular fluorinated designer amphetamine in the series.
4-Fluoromethamphetamine buy 4-FMA is a synthetic molecule of the substituted amphetamine family. Molecules of this class contain a phenethylamine core featuring a phenyl ring bound to an amino (NH2) group through an ethyl chain with an additional methyl substitution at Rα. The term “amphetamine” is the contracted form of alpha-methylphenethylamine. 4-fluoromethamphetamine contains a fluorine atom at R4 of its phenyl ring and is therefore a fluorinated analogue of methamphetamine.
4FMA,Similar to its structural analog 4-FA, 4-Fluoromethamphetamine buy is thought to act as a releasing agent and reuptake inhibitor of dopamine, serotonin, and norepinephrine, producing stimulating amphetamine-like effects at lower doses and moderate euphoric, entactogenic effects similar to MDMA at dosages above 125mg, albeit much less mild. The mechanism of action of 4-FMA effectively boosts the levels of the norepinephrine, dopamine, and serotonin neurotransmitters in higher doses in the brain by binding to and partially blocking the transporter proteins that normally clear these monoamines from the synaptic cleft. This allows dopamine, norepinephrine, and serotonin to accumulate within various regions of the brain, including its reward pathways, resulting in stimulating, euphoric and entactogenic effects.

It’s generally described as a cross between amphetamine and MDMA. The effects are cleaner and more entactogenic than amphetamine, but definitely not as entactogenic as MDMA.
The wakefulness is equivalent to or greater than MDMA, as is the case with some of the pro-social effects. Users don’t report the stimulation to be very forced or uncomfortable in most cases.
As was already mentioned, the effects are dose-dependent. It’ll be primarily like amphetamine under 100 mg and a bit more MDMA-like over 100 mg.
Users tend to report a calm mindset with the drug and the chance of anxiety or agitation appears lower than with amphetamine. It’s often very pro-social with common or strong doses. An MDMA-like floatiness may be present.
The effects often have a wave-like nature, meaning there can be short periods where it feels like you’re much closer to sober. 4-FA has a smooth onset period and typically doesn’t produce a negative comedown or strong negative day-after effects.
If you’re taking a more recreational amount, the main effects will last 4-5 hours and be followed by more amphetamine-like stimulation for a few more hours.
It’s not going to be particularly useful as a productive stimulant when over 100 mg is used. Around 50 to 75 mg is reportedly useful as a productivity aid, similarly to common amounts of amphetamine. Also, it may be productive once the core entactogenic-like effects have worn off with higher doses.
A 2015 survey of 249 people in the Netherlands gives some idea of the typical effects and how 4-FA is used. Most people reported taking it in festivals, dance parties, and clubs. They primarily obtained it through friends or online shops.
77.1% used the drug because of its specific effects, not because of its legal status. Most participants first reported taking it around 2013.
Oral was the most common route of administration (92.8%). 100 – 150 mg was the most common dose range, though close to 20% used over 150 mg.
Participants said it lasted either 4 to 6 hours or 6 to 8 hours.
The actual effect scores were between those for MDMA and amphetamine.
Compared to amphetamine
- Less irritability
- Greater talkative and pro-social effects
- Lower “craving” score
- Similar for alertness and stimulation
- Greater euphoria and “connectedness to others”
- Greater “changes in sensory perception.”
Compared to MDMA
- Lower intensity, confusion, and dizziness
- Lower “craving”
- Lower euphoria and “connectedness to others”
- Lower “changes in sensory perception.”
