5-APB5-(2-Aminopropyl)benzofuran (commonly known as 5-APB) is a lesser-known entactogen of the benzofuran class that produces MDA-like entactogenic and stimulating effects when administered. It is structurally related to entactogens like 5-MAPB, 6-APB, and MDA.Compared to other members of its family such as 6-APB and 5-MAPB, this compound in particular is known for its stimulating and euphoric effects which has resulted in its rise in popularity as a product which is easily accessible through the use of online research chemical vendors. It has been commercially distributed as a designer drug alternative to MDMA since 2010.5-(2-aminopropyl)benzofuran, also known as 5-APB, is a benzofuran and phenethylamine, meaning it has an ethylamine chain and a furan ring attached to the core benzene ring. It can also be classified as an amphetamine derivative because the ethylamine chain is alpha methylated.5-APB is a triple reuptake inhibitor for norepinephrine, dopamine and serotonin as well as being an agonist for the 5-HT2A and 5-HT2B receptors. It has also been speculated that 5-APB acts as a releasing agent for the previously mentioned neurotransmitters.This means it effectively boosts the levels of the serotonin, norepinephrine and dopamine neurotransmitters in the brain by binding to and partially blocking the transporter proteins that normally remove those monoamines from the synaptic cleft. This allows dopamine and norepinephrine to accumulate within the brain, resulting in stimulating and euphoric effects.Physical effects Stimulation Abnormal heartbeat Increased heart rate Muscle contractions Increased perspiration Dehydration Appetite suppression Nausea Temporary erectile dysfunction5-APB is sold for research purposes only and is not be utilized for any other purposes.
