5-MeO-α-ET is a tryptamine that produces psychedelic, entactogenic, and stimulant effects.



5-MeO-α-ET is short for 5-methoxy-alpha-ethyltryptamine. The full name of the chemical is 1-(5-methoxy-1H-indol-3-yl)butan-2-amine. 5-MeO-α-ET is a tryptamine, which belong to a larger family of compounds known as indolethylamines. 5-MeO-α-ET is closely related to the compounds 5-MeO-AMT and α-ET.


5-MeO-α-ET, when used recreationally, is usually taken orally at dosages of 50-75 mg.


5-MeO-α-ET produces entactogenic and stimulant effects that can last 4-6 hours. However, little information exists on the psychopharmacological of this compound, thus considerable variation with regard to dosage and effects can be expected.


There have been no reported deaths or hospitalizations from 5-MeO-α-ET, but its safety profile is unknown.


5-MeO-α-ET is unscheduled and uncontrolled in the United States, but possession and sales of 5-MeO-α-ET could be prosecuted under the Federal Analog Act because of its structural similarities to α-ET and α-MT.
