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.

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.

4-Fluoroamphetamine (4-FA), also called 4-FMP, PAL-303, Flux, 4-Fluor, 4-Flava, or 4-F, is an amphetamine type stimulant that inhibits norepinephrine, dopamine, and serotonin reuptake in the synaptic cleft of neurons. 1 Street 4-FA is available as a racemic mixture.

4-FA is a ring-substituted derivative of amfetamine, which is listed in Schedule II of the United Nations Convention on Psychotropic Substances of 1971. In nonclinical studies, 4-FA has been found to share several effects produced by psychostimulants that are predictive of abuse liability.

4-Fluoromethamphetamine (4-FMA) is a stimulant drug related to methamphetamine and 4-fluoroamphetamine. It has been reported to be sold as a designer drug, but little is known about its pharmacology or toxicology. [2]

2017年8月4日 · Are you interested in 4-fa, also known as 4-fluoroamphetamine or 4-FMP? In this total guide to 4-fa, we’ll go over what this research chemical is, if 4-fa is legal, and if it’s safe. We’ll also discuss what taking 4-fa is like and how to procure and take 4-fa yourself while minimizing risk, including guidelines on 4-fa dosage.

Data indicate that 4-FA may be able to inhibit monoamine oxidase and that it functions as a substrate-type releasing agent of dopamine, norepinephrine and serotonin. It has been shown to display amphetamine-like features in vivo and in vitro, which suggests that abuse liability might extend to humans.

2012年1月14日 · 4-FA (4-Fluoroamphetamine) also known as para-fluoroamphetamine is a research chemical and substituted-amphetamine of the phenethylamine class. It produces both stimulant and entactogenic effects that are somewhat comparable to MDMA .

4-FA is 2x more potent than 4-chloroamphetamine as a dopamine reuptake inhibitor and 13x less potent as a serotonin reuptake inhibitor. There appears to be some minor MAOI activity, though the potency is lower than 4-chloroamphetamine and 4-bromoamphetamine.

4-Fluoroamphetamine is a synthetic stimulant with some empathogenic properties. It has been commercially available on the research chemical market since 2001 but increased in popularity with the new wave of euphoric stimulants in the late 2000s.
