    Summary dose.wiki

    Rodent and cell data show 9-Me-BC up-regulates tyrosine hydroxylase and BDNF, promotes neurite outgrowth, and reverses rotenone/MPTP dopaminergic injury. IC50 ≈1 µM (MAO-A) and 15 µM (MAO-B) imply mild dietary tyramine sensitivity. Users report subtle but clean motivation, pattern-recognition boost, and mood brightening; bitterness limits sublingual dwell time.

    Dose basis. Human dosing is not established in clinical literature; values below are aggregated from community reports and should be treated as anecdotal. Start at the low end due to possible MAO-A/B inhibition and interindividual sensitivity. Anecdotal ROA. Users frequently report marked bitterness and transient mucosal burning/numbness; avoid prolonged mucosal contact if irritation occurs. Consider diluting in PEG-400/ethanol rather than DMSO to reduce sting. Do not use if you have oral lesions. (Dose figures and this note are from Drugs.Wiki.)

Oral dose (mg): threshold 5 · light 5-10 · common 10-25 · strong 25-40 · heavy 40+
Sublingual dose (mg): threshold 2 · light 2-10 · common 10-25 · strong 25-35 · heavy 35+

Oral duration: onset 0.5-1.5h · peak 2-4h · offset 3-6h · total 5.5-11.5h · after-effects 12-24h
Sublingual duration: onset 10-30m · peak 2-4h · offset 3-6h · total 5.17-10.5h · after-effects 12-24h
Insufflated duration: onset 5-15m · peak 2-4h · offset 3-6h · total 5.08-10.25h · after-effects 12-24h

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 ~ 17.5 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

    Tolerance Decay

    Full tolerance 10d Half tolerance 4d Baseline ~10d

    Tolerance pattern is inferred from community cycles and MAOI-class experience; no formal human data. Anecdotally, consecutive heavy dosing for a week can blunt effects; spacing doses and cycling (≤14 days on, ≥14 off) is commonly used to mitigate this.
