Summary
4-Cl-MAR is a novel halogenated aminorex derivative with virtually no human safety data. Halogenated aminorexes may share neurotoxicity concerns seen with halogenated amphetamines. Anecdotal reports suggest inconsistent batch potency and minimal euphoria at doses below 150 mg. Given aminorex's history of causing pulmonary hypertension, exercise extreme caution. Always start with threshold doses and employ comprehensive harm reduction practices.
