5-APB
5-APB is a synthetic entactogen of the benzofuran and substituted amphetamine classes that produces MDA-like empathogenic and stimulating effects. First synthesized by David Nichols in 1993 as a potential non-neurotoxic alternative to MDMA, it emerged as a designer drug around 2010, marketed alongside related benzofurans under the name "Benzofury." Compared to relatives like 6-APB and 5-MAPB, 5-APB is noted for being particularly stimulating and euphoric. It is commonly found as succinate or hydrochloride salts, which differ in potency by mass.
