BUY 4-Fluoroamphetamine Crystal 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 and 4-fluoromethamphetamine.
4-Fluoroamphetamine is a substituted amphetamine that offers effects somewhere between those of amphetamine and MDMA. Its been a member of the research chemical market since the late 2000s.
It has at times been a more popular research chemical because it does have a unique and potentially desirable effect profile.
Not enough is known about the drug to be sure about its safety level, particularly with chronic use.
4-Fluoroamphetamine (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 LD50 (mouse; i.p.) of 4-FA is 46 mg/kg.
4-FA has only been involved in one death worldwide, where it was combined with amphetamine, methadone and benzodiazepines.
4-Fluoroamphetamine is a releasing agent and reuptake inhibitor of dopamine, serotonin, and norepinephrine. The respective EC50 values are 2.0 x 10?7 M, 7.3 x 10?7 M, and 0.37 x 10?7 M, while the IC50 values are 7.7 x 10?7 M, 68 x 10?7 M, and 4.2 x 10?7 M.
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. As a recreational drug, 4-FA is sometimes sold along with related compounds such as 2-fluoroamphetamine and 4-fluoromethamphetamine.
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.
