Clobromazolam, AKA Phenazolam has appeared, seemingly as an alternative to bromazolam.
From Wikipedia:
Phenazolam, (Clobromazolam, DM-II-90, BRN 4550445) is a benzodiazepine derivative which acts as a potent sedative and hypnotic drug. It was first invented in the early 1980s, but was never developed for medical use. It has been sold over the internet as a designer drug, first being identified in seized samples by a laboratory in Sweden in March 2016.
Here is a rough dosing guide and write up posted on this Reddit thread that seems to be about the best information available currently -- Don't take this as gospel though, start small as possible anytime you take a new substance, regardless of your perceived tolerance to sedatives or anything else.
________________________________________________________________________________________
My conclusions are as follows: ~0.25 mg/250 ug clobromazolam / phenazolam = 10 mg diazepam = 0.2 mg/200 ug clonazolam = 0.5 mg alprazolam. In other words, clobromazolam is 40x more potent than diazepam/Valium, twice as potent as alprazolam/Xanax, and only slightly less potent than clonazolam.
This conclusion has horrific implications: all the clobromazolam presses I’ve seen floating around have been dosed between 2-3 mg. Of course, these pills are manufactured in clandestine labs without regulations, so the actual dosage may vary quite a bit. However, if the presses contain even 2 mg of clobromazolam, that means a single pill is equivalent to 4 mg alprazolam or 80 mg diazepam. For reference, common doses of alprazolam and diazepam, by Psychonaut Wiki’s standards, are 0.5-1.5 mg and 5-15 mg, respectively. For almost everyone on Earth, this is a ridiculously high dosage. It is incredibly irresponsible that presses are being dosed this high. Most people would assume a single pill is a perfectly normal dose: in this case, it is at least 3 times, and up to 16 times, more than a common dose. One, or even half of these presses could easily cause a blackout or, depending on what’s in your system or where you are, kill you. There is also the even more possibility that some presses are MORE potent than advertised – which is indescribably terrifying.
Crucially, the onset time is 1 hour-1.5 hours; the total duration is between 8-14 hours (average: ~11 hours). I repeat: it takes an hour or more to fully feel the effects. Combined with its ridiculous potency, this is what makes clobromazolam so dangerous. Since it takes so long to kick in, people are very likely to re-dose before they even feel the effects of the first dose – and bear in mind, clobromazolam is fourty times more potent than diazepam. With each re-dose, the likelihood of blackouts and overdoses skyrockets. While fatal overdoses from benzos alone are very rare, when combined with alcohol, opioids, barbiturates, etc., an overdose is both much more likely and exponentially more likely to kill you. For the love of God, do not mix clobromazolam with any other CNS depressants.

Anecdotally, I have tried a bit of this now. I've had about 3 mgs over the last 24 hours or so. I'm not particularly intoxicated, but they're definitely a good feeling. Like the other guy said, they seem to be a longer lasting type of benzo, that takes a while to fully kick in. I have just been taking doses of .5mg.
Benzos are sort of unremarkable and hard to describe for me, but it feels a little bit more lucid and less physically sedating than bromazolam. But idk, yesterday when i first took it was coming down from an ecstasy roll, and today I've had some amphetamine, thc, cbd, and kratom as well.
I'll definitely update further as I get to know the substance, but there didn't seem to be a lot of info on this so I wanted to make a thread for it
