Also known as 2,5-DIMETHOXY-4-BROMOAMPHETAMINE

A landmark for its unprecedentedly high potency, active near 2 mg, very long-lasting, and a thoroughgoing psychedelic. Despite a large safety margin in mice, it has caused human tragedies including fatal overdose, convulsions, prolonged coma, and arterial spasm, often when users mistook it for MDA and took a far too large dose.
