Weird, though I'm not terribly surprised. I know amanitas/muscimol are a thing that are being sold, but I don't really think there is enough biomass available to be stocking headshops nationwide. They are totally different effect IMO, and also wouldn't be terribly surprised if there was some amount of benzo in there considering the availability of RC benzos these days.
Somewhat recently, admittedly after the explosion of amanita gummies in headshops / advertising on social media etc etc, one large Chinese RC vendor started listing kilograms of muscimol. So many of these gummies could just be using synthetic muscimol rather than actual Amanita extract.
And there's a fairly rigorous proof from a chemist on reddit that one brand of "muscimol isolate" is actually just pregabalin as the active:
Different person sent a sample to DrugsData: https://www.drugsdata.org/view.php?id=17152
So there's definitely some fuckery about. I wouldn't be shocked that someone would use a 4 sub tryptamine in gummies too.
