    Summary TheDrug.Wiki

    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.

    Tolerance

    Build-up develops over days to weeks of regular use
    Reset 3–7 days for acute; 1–3 weeks for full reset

    Tolerance Decay

    Full tolerance 1d Half tolerance 3d Baseline ~21d

    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.
