5-Methoxy Alpha-Methyltryptamine (5-MeO-aMT)

5-MeO-AMT a potent psychedelic tryptamine. It is soluble in alcohol.The sympathomimetic effects may in turn be caused by 5-MeO-AMT's structural similarity to the amphetamines. As noted by Alexander Shulgin, the alpha-methylated tryptamines can be looked at as the tryptamine homologues of the amphetamines (alpha-methylated phenethylamines).

It is supposedly sold in 4 mg tablets by the street nameAlpha-O and taken as a recreational drug. Since the DEA arrests of the makers of a huge percentage of the United States' LSD in 2000, 5-MeO-AMT may have occasionally been sold under the guise of LSD in liquid, sugar cube, or blotter form. Although this idea may be because the DEA has released reports of finding it on sugar cubes, and blotters, "LSD Style".The most common route of administration for 5-MeO-AMT is orally, however anecdotal reports have stated less common methods such as snorting or smoking.
