_____________ My background: _____________ 25, male (ish), I have used probably like 80 chemicals, heroic doses of psychs and dissociative benders, a small handful of different benzos, plenty of phenibut, gabapentin, etc. I could keep going but I don't find it necessary or relevant.

Summary
Pyrazolam is a novel depressant substance of the benzodiazepine class. Pyrazolam was originally developed at Hoffman-La Roche in the 1970s and subsequently "rediscovered" and sold as a research chemical starting in 2012. Subjective effects include sedation, anxiety suppression, muscle relaxation, disinhibition, and euphoria.

Based on reports from:
Tolerance
Build-up
develops over 1โ4 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
7d
Baseline
~21d
Acute tolerance: develops within a single session โ the reset numbers above apply after sustained heavy use, not after one binge. Within-session tachyphylaxis usually resets largely overnight.
As with other benzodiazepines, tolerance to sedative/hypnotic effects can build within days of repeated dosing; anxiolytic tolerance may develop more gradually. Rough recovery to baseline often requires several weeks off. Estimates here are conservative and based on general benzo patterns and user reports, not controlled studies.

I will give you an outline of how I used Pyrazolam, its effect and a good way to beat the grogginess the next morning (The first paragraph is just about me ย if you like, you can skip it, and the cure for grogginess is at the bottom of the page). Firstly, I would like to tell you the reason why I took Pyrazolam.

Having experienced other short-acting triazolobenzodiazepines ranging from Alprazolam to Etizolam (yes, I know it's technically a Triazolothienodiazepine, but virtually identical in effect), I found both to be unusually euphoric as far as the benzos are concerned, since my usual (prescribed) benzo of choice is diazepam...
This is my experience with pyrazolam, a kinda 'novel' benzodiazepine that's kinda new to the RC market from what I have read. I obtained this actually for the purpose of helping me go through opioid withdrawal.

Hi, I'm a mid 30ish male who quite enjoys the odd benzo from time to time, especially when drinking (in strict moderation, and with the benzos put away!) I've tried a good few benzos now, valium, xanax, etizolam, pyrazolam, temazepam and the newish diclazepam (which is mostly indistinguishable from valium for me, but m...
Briefly, i as a younger more imprssionable guinea pig i decieded doing all the drugs all the time cant go wrong until then it did. Thankfully i manage to salvage my respect and regain my sanity somewhat.
