What is 4B-MAR Powder?
4B-MAR (4-Bromo-Methylaminorex) is a synthetic stimulant research chemical belonging to the aminorex class. It is chemically similar to 4-Methylaminorex but contains a bromine atom added at the 4-position on the phenyl ring. This small change introduces unique chemical properties while retaining stimulant effects. 4B-MAR acts mainly by releasing and enhancing the effects of monoamine neurotransmitters such as dopamine and norepinephrine. It is provided as a powder suitable for neuropharmacology, behavioral research, and analytical studies.
