4-Fluoro-amphetamine (4-FA; “Flux”; para-fluoro-amphetamine; Flux), also known as 4-fluorophenylaminopropane, is a psychoactive substance . It is an agonist of both dopamine and serotonin receptors. It has a stimulating effect, similar to amphetamine and relaxing, similar to 4-methylamphetamine , with psychedelic effects and more pronounced euphoria. 4-fluoro-amphetamine is relatively rare in the illegal market, since a 4-substituted precursor is required in production (for amphetamine it’s usually unsubstituted, it is much cheaper), and its synthesis reaction yields are lower than for classical amphetamine.

Dosage
Dosage varies by users depending on the desired effect. The usual dosage is 75-150 mg. Tests have shown that to achieve the same effects, using the substance intravenously, subjects required 60% of the oral dosage .
4-fluoro-amphetamine is almost impossible to take intranasally (inhaling through the nose) due to the sharp taste and burning sensation in the nose .
