    Summary dose.wiki TripSit PsychonautWiki

    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.

    Tolerance

    Build-up develops over 1โ€“4 weeks of daily use; hypnotic tolerance faster than anxiolytic tolerance
    Reset Falls after you stop, at a rate that varies from person to person. If you've been using regularly, cut down gradually with medical help rather than stopping suddenly.

    No tolerance chart. Our decay curves for these drugs were estimates, and a curve can make tolerance look longer-lasting than it is, which is the dangerous direction.

    How fast tolerance to these drugs fades after a break has not been measured well enough to draw, so don't count on a dose you used to take still being safe: after time off, start with a much smaller amount and don't use alone. Mixing sedatives with each other, with alcohol or with opioids sharply raises the risk of a fatal overdose. If you've been using regularly, don't stop suddenly: withdrawal from benzodiazepines, alcohol or GHB/GBL can cause seizures or delirium, so get medical help to cut down gradually.

    Effects Erowid

    Aggregated from 5 single-substance Erowid experience reports; 4 Erowid reports where another drug was taken too are left out

    Each bar shows the share of analyzed reports whose text mentions that effect — a mention is not always a first-hand experience (fear of an effect or something witnessed can count). Mentions saying the effect did not happen are left out; that check reads keywords, so it can miss some. The shaded band on a bar, and the small range after its number, is the 95% interval: where the share could plausibly be with other reports of the same kind. Fewer reports, wider band. Tap or hover any number for details. The second value is the Bluelight extractor's per-effect confidence; a dash means the row is Erowid-derived, which has no confidence measurement.

    Too few reports for bars: these effects come from 5 single-substance Erowid reports, and a bar is drawn only from 20 reports or more. With fewer, a percentage cannot tell a common effect from a rare one. Counts are shown instead. Why 20?

    Also reported in combinations. In the 4 Pyrazolam reports where another drug was taken too, 1 mentions hospital, emergency services or an overdose, 0 a seizure and 1 psychosis (too few reports for percentages). In the 5 single-substance reports: 0, 0 and 0. These are not in the figures above: they cannot be put down to Pyrazolam alone, and a mention is not always something that happened to the writer.

    _____________ 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.

    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.
