Aliases: 4-mbc, 4-methyl-n-benzylcathinone, N-benzyl-4-methylcathinone, Para-methyl-n-benzylcathinone
Summary
Limited human data—treat as an experimental research chemical. Appears to act as a prodrug to 4-methylcathinone (not mephedrone) via N-debenzylation, with markedly lower potency and euphoria than mephedrone. Prominent peripheral stimulation (tachycardia, vasoconstriction) with comparatively subtle empathogenic qualities.

Based on reports from:
Tolerance
Build-up
develops rapidly, often within a single session; compulsive redosing common
Reset
a few days for acute tolerance
Tolerance Decay
Full tolerance
2d
Half tolerance
4d
Baseline
~14d
Pattern inferred from cathinone/amphetamine use reports: tolerance builds over multi‑day use and decays over 1–3 weeks of abstinence. Data quality is anecdotal; avoid consecutive‑day or binge use.
