    Summary dose.wiki

    2C-BZ is an extremely rare or possibly 'phantom' compound with no verified analytical confirmations in published literature. The compound has never been positively identified in seized samples, and anecdotal reports cannot be confirmed. If the compound exists, it would theoretically be the phenethylamine analogue of 3C-BZ (which is documented in PiHKAL).

    Dose Information dose.wiki Drugs.Wiki

    Dose basis. Ranges are anecdotal and assume the material is the same entity; many samples sold as “2C‑BZ” have not been analytically confirmed. Use a calibrated 0.001 g (mg) scale; prefer volumetric dosing for single‑digit milligram amounts. Start with an allergy test of 0.5–1 mg and wait a full 2–3 hours before considering any increase due to variable 2C‑x onsets and unknown potency. Guidance reflects harm‑reduction principles rather than endorsement. Sources: TripSit dosing cautions and general factsheet guidance; 2C‑E onset variability illustrates the need to wait before redosing. (Dose figures and this note are from Drugs.Wiki.)

    The PsychonautWiki Journal logging app doesn't include every substance. To track 2C-BZ there, start adding an ingestion, search for the name, and choose to add it as a custom substance. Paste these values:

    Description 
    2C-BZ
Source: SubstanceSearch (substancesearch.com)

Oral dose (mg): threshold 1-2 · light 2-4 · common 4-8 · strong 8-12 · heavy 12+ (NOT ADVISED)

Oral duration: onset 0.5-1.5h · come-up 1-2h · peak 2-4h · offset 3-5h · total 6.5-12.5h · after-effects 1-3h

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 ~ 6 mg (Oral).

    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.

    Tolerance

    Build-up develops rapidly after a single use
    Reset 7–14 days for baseline

    Tolerance Decay

    Full tolerance 12h Half tolerance 7d Baseline ~14d

    Pattern inferred from classical psychedelic tolerance: marked acute tolerance develops after a single strong session and decays over ~1–2 weeks; exact kinetics for “2C‑BZ” are unknown and based on analogy/anecdote.
