    Summary TheDrug.Wiki TripSit PsychonautWiki

    Theacrine is a structural analog of caffeine with about two-thirds the potency for stimulation but stronger effects on focus. It has a biphasic dose-response: low doses may be sedating while higher doses are stimulating. Unlike caffeine, theacrine does not appear to significantly affect blood pressure.

    Theacrine Accidental Overdose Experienced Very Unexpected cautionary

    Last night I accidentally took over 900 mg of theacrine. Almost a gram. I took it with gotu kola, about two teaspoons of an extract with 5% saponins. I believed I was taking L-Theanine , which has almost no noticeable effect on me. I was trying to coax a high out of my gotu kola after building tolerence.
