Summary
Flubromazolam (JYI-73) is a novel synthetic depressant substance of the benzodiazepine, and specifically, the triazolobenzodiazepine class which produces anxiolytic, disinhibiting, sedative, muscle relaxant, and memory suppressing effects when administered. It is incredibly potent (active in the microgram range) with an unusually long 18 hour duration. Thus, it poses comparatively higher risks than other designer benzodiazepines, due to its ability to produce strong sedation and amnesia even at a very low threshold dosage.

[This report is a continuation of another one, A Unexpected Surprise In My Mailbox , submitted the same day.] I used 0.25mg of flubromazolam for a couple months each day after work. It was mild to me I enjoyed it and did abuse it. I ran out and was waiting for more to come in.
A lot of information available is pretty daunting on first discovery of said substance. And itΒs definitely true what is said about liquid and volumetric dosing. That said with the substance eyeballed in such a way so as to not vastly exceed the mg range. ItΒs a creeper. ItΒs strong.
I try to be descriptive in my reports, but that isn't really possible here. I'll expand as much as I can. Background/Notes: I'm pretty experienced with drugs, done every class multiple times at different doses. I like them all, from stims to deliriants and everything in between.
So let me clarify, yes this was a dose of 30 MILLIGRAMS, NO IT WAS NOT AN INTENTIONAL DOSE.... I was using flubro for about 2-3 weeks, I was pretty experienced with benzos, using alpraz, etiz and clonazolam/pam daily, I thought I had a tolerance to these but flubro taught me I was laughing at the devil to his face tryi...

Being related to triazolam and alprazolam, its potency has been described as "as potent as Triazolam, twice as potent as alprazolam or flunitrazepam and 'considerably more...
