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.

Effect Profile
Scores (1–10) curated from multiple sources:
- Effect keyword matching from PsychonautWiki catalog
- Weighted by importance: core (×3), major (×2), minor (×1)
Strong anxiety/jitters and stimulation with moderate focus, mild euphoria
Tolerance
Tolerance Decay
Acute tolerance: develops within a single session — the reset numbers above apply after sustained heavy use, not after one binge. Within-session tachyphylaxis usually resets largely overnight.
Model reflects general stimulant patterns and self‑reports; exact kinetics unknown for 4C‑MAR.
