It might be ADB BUTINACA, shortened to ADB-B. If so, It is a potent agonist of the CB1 receptor and CB2 receptor with EC50 values of 0.52 nM and 0.88 nM respectively.
I found a listing of ADB BUTINACA ( adbb ) on an RC site. It is newish as of December, 2019. *If* it is this compound, someone had a seizure on 1 mg oral. If it's just the price difference, it isn't worth it in my opinion. I read of 1 possible death due to coronary thrombosis. Assume it's poison and please throw it out.
