BUY 4-FA POWDER 4-Fluoroamphetamine (4-FA; 4-FMP; PAL-303; Flux), also known as para-fluoroamphetamine
(PFA) is a psychoactive research chemical of the phenethylamine and substituted amphetamine chemical classes.
It produces stimulant and entactogenic effects, and is described subjectively as being between amphetamine and
MDMA. As a recreational drug, 4-FA is sometimes sold along with related compounds such as 2-fluoroamphetamine
Molecular formula: C9H12FN
Total: 4 7 hours (at least somewhat longer for the stimulation vs. entactogen activity)
Onset: 20 40 minutes
4-FA is popular in the Netherlands where it is predominantly used for its specific effects (77% of users) rather than its legal status (18%). 4-FA has become illegal since May 2017.
The subjective effects of 4-fluoroamphetamine include euphoria which some find similar to the effects of MDMA and
amphetamine, increased energy (stimulation), mood elevation, feelings of warmth and empathy, excessive talking,
bruxism, and suppressed appetite (anorexic). The general course of effects involves primarily empathogenic effects
for the first few hours, which fades out as increased stimulation develops over the next several hours.
The dopamine reuptake inhibition produced by 4-FA is stronger than that of either 4-CA or 4-IA. 4-FA also produces less hyperthermia than similar compounds such as PMA, 3-MTA and 4-methylamphetamine.
Common acute side effects are nausea, headaches, increased heart rate and insomnia.
4-Fluoroamphetamine (also known as 4-FA, 4-FMP, para-Fluoroamphetamine, PAL-303 and colloquially
as Flux) is a novel synthetic amphetamine compound that produces a unique progressive mixture
of entactogenic and stimulant effects when administered. It is part of a series of fluorinated amphetamine analog that
initially included such compounds as 2-FA, 2-FMA, and 3-FA.
Anecdotal reports have described the subjective effects of 4-FA as having a moderate MDMA-like entactogenic onset
for the initial few hours of the experience that then gradually transitions into traditional amphetamine-
type stimulation (for a total duration of around 6 to 8 hours) with residual effects that can last a few hours afterward.
4-FA is rarely found on the streets but was commonly sold as a grey area research chemical by online vendors along
with related compounds such as 2-FMA and 3-FA. Very little data exists about the pharmacological properties,
metabolism, and toxicity of 4-FA, and it has only a brief history of human usage. Due to its strong psychostimulant
effects, likely habit-forming properties as well as poorly understood toxicity profile, it is strongly recommended that
one use proper harm reduction practices if choosing to use this substance.
