    TMA-2 structure

    Summary TheDrug.Wiki TripSit PsychonautWiki

    TMA-2 is a synthetic psychedelic amphetamine that is notably more potent than its positional isomer TMA (3,4,5-trimethoxyamphetamine). It has a limited history of human use and is known for producing unique stimulating effects with less pronounced visual distortions compared to mescaline. Anecdotal reports indicate TMA-2 is dose-sensitive and can produce uncomfortable body load, nausea, and overstimulation. The substance is rarely available on the street market and is primarily obtained as a research chemical. Legal status varies by jurisdiction; it is Schedule I in the United States and controlled in many European countries.

    Perspectives

    “TMA-2 is a challenging but rewarding experience, worthwhile for those willing to suffer the massive lingering bodyload and the overwrought, nonstop stimulation.”

    “I took it in two 10 milligram doses, spaced by two hours. There was a slight movement of surface textures, my hearing was deepened and spatially defined. The body was relaxed and stretching seemed necessary. The further I got into it the more I realized that I was totally lazy. Very lethargic, to the point of laughter. At the sixth hour, I was seeing more life in the woodwork, and the wooden angel hanging on the ceiling was flesh and feathers when I stared at it. Great vision. But by no means overwhelming. Sleep was fine.”
