    Summary TheDrug.Wiki TripSit PsychonautWiki

    2-FEA has minimal formal research and all dosage guidance derives from anecdotal user reports. The effects are subtle and variable, with some users reporting mild stimulation similar to 2-FA and others noting increased serotonergic activity. Analytical confirmation via GC-MS or reagent testing is essential as 2-FEA is visually indistinguishable from similar compounds. Main acute risks include hypertension, tachycardia, vasoconstriction, and potential serotonin syndrome when combined with other serotonergic substances. Use harm reduction practices including limiting frequency to no more than once weekly.
