Sublingual dose (µg): threshold 500ug · light 1000-1500ug · common 1500-2000ug · heavy 2000ug+

Buccal duration: onset 30-50m · peak 5-7h · total 5-7h · after-effects 1-2h

Note: ranges are harm-reduction guidance, not a prescription. Start low, go slow, and test your substances.

    Tip: for quicker logging you can also add a Custom Unit in the app, e.g. common dose ~ 1750 µg (Buccal).

    The app keeps custom substances simple, so the full dose ranges live in the description text above. Ranges are harm-reduction guidance, not a prescription.

    This was our first experience with a new supplier so we were all a bit apprehensive as to the quality of the tabs. We were told that they contained around 700µg of 25G-NBOMe.
