    Summary TheDrug.Wiki Erowid TripSit PsychonautWiki

    AMT is a long-acting psychedelic stimulant with significant body load and powerful nausea during onset. At higher doses (approaching 150 mg), it acts as a reversible MAOI, greatly increasing the risk of serotonin syndrome when combined with other serotonergic substances. Effects can take over 2 hours to fully develop; redosing prematurely has led to dangerous overdoses.

    Perspectives

    “I got a strong psychedelic experience that lasted about twelve hours, but an unexpected relief from my chronic depression that lasted for four days.”

    “If it was still accessible I would probably sample this again, but under significantly different conditions.”
