3-MAR
Summary
3-MAR produces a clear, focused stimulation reminiscent of 4-MAR but with more pronounced head pressure and emotional lability. Users describe strong synergy with amphetamine yet diminishing returns when redosed in isolation. Nasal administration is sharply caustic; vaporizing the freebase yields a rapid rush but encourages compulsive re-administration.

Anecdotal: tolerance rises rapidly during a binge and partially recovers after 3–5 days; baseline by 7–14 days if no further use. Cross‑tolerance with other aminorex derivatives and common stimulants is likely but unquantified.
