    Psychedelic Empathogen Research-chemical

    Summary TripSit

    A rather rare psychedelic phenylethylamine that is the hydroxylated version and prodrug for 2C-T-7.

    Perspectives

    “I am lightheaded, and maybe a little tipsy. I am well centered, but I don’t want to go outside and meet people. Shades of alcohol woozy. The effects were going already by the fifth hour and were gone by the seventh hour. I would call it smoothly stoning.”

    This is an old report i did years ago. I figured I'd post it here, for the archive I just spent a good amount of time writing this up on another forum, so I thought that I would also post it here. I did originally post it on a site that doesn't allow Human Consumption talk.
