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. Reports emphasize hydration (0.5 L per hour isotonic) and magnesium (200-400 mg) to reduce teeth grinding and vasoconstriction. Because the market is extremely limited, mis-sold material is common; verify identity with GC-MS or FT-IR where possible.
