Desalkylgidazepam (CAS 2894-61-3) An Analytical Reference Standard www.caymanchem.com Had a chance to do a bit of experimenting with this the other day, and it was interesting. I know it's been reported to have a very long half life, which appears to be the case based on my experiences.

Summary
Bromonordiazepam (also called desalkylgidazepam) is the active metabolite of the Ukrainian anxiolytic gidazepam and is now sold online as a long-acting research chemical benzodiazepine. Recreational users estimate approximately 6 mg equals 10 mg diazepam, placing it at roughly 0.6× diazepam potency. Light anxiolysis emerges at 3-6 mg, while sleep-inducing doses of 15 mg and above risk prolonged psychomotor impairment the next day.

Description
Bromonordiazepam Source: SubstanceSearch (substancesearch.com) Oral dose (mg): threshold 2 Oral duration: onset 0.33-1h · come-up 0.5-1.5h · peak 2-4h · offset 3-6h · total 5.83-12.5h · after-effects 12-48h Note: ranges are harm-reduction guidance, not a prescription. Start low, go slow, and test your substances.
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 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
37d
Baseline
~60d
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.
