    Stimulant

    Summary

    MMDA is a stimulant. Reported effects include euphoria, color enhancement, time distortion, and wakefulness. Limited data is available on its dosage and safety profile.

    Perspectives

    “I felt completely relaxed at one hour. Almost as if I was floating. There were no obvious effects on taste, and the relaxation and composed feeling is much like a small dose, maybe 20 mikes, of LSD. There was some dilation, and in the evening I was a little restless and slightly tired. I slept well, and awoke refreshed and happy.”

    Like Swimming in a Warm Ocean Full of Love positive exp #117164

    I was very interested in trying MMDA after reading a few of the scarce trip reports online and Shulgin's reports. Easygoing euphoria with intense "mind movie" CEVs sounded incredible.

    June 4th, 2010 3-methoxy-4,5-methylendioxyamphetamine Dosage: 195mg Prologue: MMDA looks appealing just based on structure alone. If one drew the structure of mescaline, then superimposed the structure of MDA over mescaline you would get MMDA. Or, you could look at it as “3-MeO-MDA”.

    Miniature High neutral exp #92427

    I use the word miniature in the sense that I would describe a piece by the jazz pianist Bud Powell as a miniature. Comparing a Beethoven piano sonata with 'Autumn in New York' as played by Powell would be analogous to comparing mescaline and MMDA.
