Summary
An entactogenic amphetamine stimulant with similar structure and effects to MDMA. An analogue of MDA, it is a highly selective serotonin releaser but inhibits reuptake of serotonin (weakly), dopamine and norepinephrine.
Perspectives
“A worthy addition to the toolkit. Perhaps its most interesting feature is its total lack of stimulation. It is psychedelic too, at least mentally.”

Not much preparation, just got off a busy busy day of work, last meal eaten was about four hours prior, a flatbread sandwich and some cholesterol free chips, nothing heavy. After an insufflated 5 milligrams for allergy testing, I weighed out 100 milligrams of 5-APDB and parachuted it in some tissue paper.
