[top]Introduction to 4-FA

4-fluoroamphetamine acts as both a releasing agent and reuptake inhibitor of dopamine, serotonin, and norepinephrine. Common names: 4-Fluoroamphetamine; 4-FMP; para-fluoroamphetamine; and RDJ.

[top]Using 4-FA

[top]Ways of Administration

The two most common routes of administration for 4-FA are intranasal and oral consumption, with oral consumption being the primary route of administration among researchers, due to the rather painful burning sensation that is accompanied with intranasal administration.

[top]Pharmacology of 4-FA

4-fluoroamphetamine is a release 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 3.7 x 10−8 M, while the IC50 values are 7.7 x 10−7 M, 6.8 x 10−6 M, and 4.2 x 10−7 M.[1]

Regarding the metabolic fate of 4-FA, it is likely excreted from the body entirely unchanged. The C-F bond at the 4-position on the phenyl ring likely resists deactivation in the liver by cytochrome P450 oxidase[2]
