    Clobromazolam

    Aliases: Dm-ii-90, Phenazolam, Brn 4550445

    Depressant Research-chemical Benzodiazepine

    Summary TheDrug.Wiki

    Phenazolam is the same compound as clobromazolam; it first appeared on the market circa 2016 and has no approved medical use. Forum meta-reports consistently place its potency at approximately 40 times that of diazepam, with 0.25 mg often compared to 10 mg diazepam or 0.5 mg alprazolam; avoid any pressed tablets claiming multi-milligram doses. Onset is notably slow for a triazolobenzodiazepine, often 1-2 hours and sometimes 3 hours, which greatly increases redosing risk and blackout potential.

    Tolerance

    Build-up develops over 1–4 weeks of daily use; hypnotic tolerance faster than anxiolytic tolerance
    Reset weeks to months depending on half-life and duration of use; taper recommended

    Tolerance Decay

    Full tolerance 3d Half tolerance 14d Baseline ~28d

    Benzodiazepine sedative/hypnotic tolerance can develop rapidly with daily use; partial reversal requires weeks to months of abstinence and is highly individualized. Data are largely anecdotal; treat any numerical model as a rough guide only. Avoid consecutive‑day use to limit tolerance and dependence risk.
