    Summary dose.wiki TripSit

    2-MEC appeared on grey-market outlets around 2012 as a mephedrone substitute, often in 'NRG-2' blends. Studies indicate 2-substituted cathinones are generally weaker than 3- or 4-substituted analogs due to steric hindrance. Users describe it as producing less empathogenic effects compared to mephedrone, with more prominent stimulation and cardiovascular strain.

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 ~ 150 mg (Oral / Sublingual).

    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 6h Half tolerance 3d Baseline ~10d

    Acute within‑session tachyphylaxis is common with cathinones; repeated redosing produces diminishing returns and a harsher comedown. Cross‑tolerance with other monoaminergic stimulants/empathogens is expected based on mechanism overlap. Waiting at least 7–14 days between sessions reduces residual tolerance and mood after‑effects.
