Around 15 years ago or so (can't remember exactly when)
My (at the time) regular acid hook up sold me some blue pressed tablets that had a picture of a bumblebee on it and had a slight indent on each pill (from pressing them slightly off of center possibly)
He expressly said this a brand new psychedelic called TCB-2.
I tried it twice before actually looking up TCB-2 and was sketched out by the potency and lack of potential saftey so I flushed them all....
About a year later I was looking online at a site that reports on pressed pills (like pillreports) and saw that they were supposedly 2c-b but the effects were absolutely nothing like any of the 2c-x series thst I've tried and I've tried most of them....I seriously doubt it was TCB-2
But ti this day I'm still very curious as to what the heck that was!
