    Summary dose.wiki

    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.

    Dose Information dose.wiki Drugs.Wiki

    Dose basis. Ranges synthesized from multiple user reports; no human PK or clinical dosing studies exist. Treat as highly uncertain; individual sensitivity varies. Sources: Bluelight reports and Drugs‑Forum discussions. User reports consistently describe harsh nasal burn and limited benefit vs oral; insufflation not advised for harm reduction. Sources: Bluelight reports. (Dose figures and this note are from Drugs.Wiki.)

Oral dose (mg): threshold 30-60 · light 100-200 · common 200-350 · strong 350-500 · heavy 500+ (not advised)
Insufflated dose (mg): threshold 10-20 · light 25-60 · common 60-120 · strong 120-200 · heavy 200+ (not advised)

Oral duration: onset 0.5-1h · come-up 0.5-1h · peak 1.5-2.5h · offset 1-2h · total 3.5-6.5h · after-effects 2-6h
Insufflated duration: onset 5-10m · come-up 10-20m · peak 1.5-2.5h · offset 1-2h · total 2.75-5h · after-effects 2-6h

Note: ranges are harm-reduction guidance, not a prescription. Start low, go slow, and test your substances.

    Tip: for quicker logging you can also add a Custom Unit in the app, e.g. common dose ~ 275 mg (Oral).

    The app keeps custom substances simple, so the full dose ranges live in the description text above. Ranges are harm-reduction guidance, not a prescription.

    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.
