5-MAPB also known as 5-(2-methylaminopropyl) benzofuran, is a synthetic entactogen of the benzofuran class. 5-MAPB is known for its stimulating, euphoric and entactogenic outcomes. 5-MAPB includes MDA-inspired substances as 5-APB, 6-APB and 5-EAPB, among others. 5-MAPB has been rising in popularity as a research chemical since 2010. 5-MAPB is structurally similar to 3,4-Methylenedioxymethamphetamine, also known as Molly or MDMA, first developed in 1912 by Merck. In theory, it acts primarily by increasing the neurotransmitters serotonin, dopamine, and noradrenaline activity and belongs to the substituted amphetamine classes. Researchers have reported that 5-MAPB has the same stimulant and hallucinogenic outcomes.
