anecdotal reports suggest that 2-fea has been compared with 3-fea, which it is thought to share many of its effects with.
2-fluoroethamphetamine (2-fea) is a synthetic molecule of the substituted amphetamine class. molecules of the amphetamine class contain a phenethylamine core featuring a phenyl ring bound to an amino (nh2) group through an ethyl chain with an additional methyl substitution at rα (i.e., amphetamines are alpha-methylated phenethylamines). 2-fea contains an ethyl group bound to the terminal amine rn of the amphetamine core.
2-fea is the n-ethylated homolog of 2-fa (2-fluoroamphetamine).
although 2-fea has not been formally studied on the same level as traditional amphetamines, it is roughly assumed that it most likely acts primarily as a triple reuptake inhibitor and/or releaser of the monoamine neurotransmitters serotonin, dopamine, and norepinephrine.
this indicates that 2-fea effectively increases the levels of all the three major monoamine neurotransmitters dopamine, norepinephrine, and serotonin in the brain by acting as a releasing agent of said neurotransmitters and/or by binding to and partially blocking the transporter proteins that normally clear those molecules from the synaptic cleft after they have fulfilled their function of conducting a neural impulse. this transporter blockade allows these molecules to accumulate within core synaptic regions of the brain to extra-endogenous levels, resulting in a combination of relaxing, stimulating, disinhibiting and euphoric effects associated with entactogenic substituted amphetamines such as mdma or 4-fa.
