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.

Summary
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.

Import into PsychonautWiki Journal
The PsychonautWiki Journal app includes Theacrine, but its built-in data can be thinner than ours. Importing this file adds a separate "Theacrine (Substance Search)" custom substance with our dose ranges, durations and tolerance, so you can log against whichever you prefer.

Import this file as custom substances
and you get "Theacrine (Substance Search)" with every
route's full dose ladder and timeline, no typing. Works on iOS and
Android (v15+); the format is confirmed by the app's
developer.
Ranges are harm-reduction guidance, not a prescription.
Tolerance
Build-up
develops over days to weeks of regular use
Reset
3–7 days for acute tolerance; longer for full reset
Tolerance Decay
Full tolerance
1d
Half tolerance
10d
Baseline
~18d
Acute tolerance: develops within a single session — the reset numbers above apply after sustained heavy use, not after one binge. Within-session tachyphylaxis usually resets largely overnight.
