Summary
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.

Effect Profile
Scores (1–10) curated from multiple sources:
- Effect keyword matching from PsychonautWiki catalog
- Weighted by importance: core (×3), major (×2), minor (×1)
Strong anxiolysis, sedation, and cognitive impairment with moderate euphoria
Tolerance
Tolerance Decay
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.
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.
