4-БА
para-Bromoamphetamine is a substituted amphetamine with stimulant and entactogenic properties that is highly neurotoxic to serotonergic neurons. Research shows it depletes brain serotonin for at least a week after administration, similar to para-chloroamphetamine. It acts as a weak MAO-A inhibitor, adding additional risks when combined with other serotonergic substances. This substance has extremely limited human use data and should be considered dangerous. Avoid all use due to severe neurotoxicity risk.
