    Depressant Research-chemical Benzodiazepine

    Summary PsychonautWiki

    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.
