    Summary dose.wiki

    3-CAF is a positional isomer of the neurotoxic para-chloramphetamine (PCA). In vitro work (Urban et al., 2012) indicates potent serotonin and moderate dopamine/noradrenaline release (EC50 ≈ 35 nM for 5-HT, 280 nM for DA). Neurotoxicity appears reduced compared with PCA but long-term serotonergic depletion has been observed in rat cortex at ≥10 mg/kg (Kindred et al., 2015).

    Dose Information Drugs.Wiki

    Dose basis. Human data are scarce; ranges largely derive from scattered user reports. Always use an accurate 0.001 g scale, consider an allergy test (≈1–2 mg), and titrate cautiously. Insufficient evidence to support frequent redosing. Faster onset with steeper cardiovascular load and more local irritation. Volumetric dosing recommended to avoid overestimation from hygroscopic powders; avoid repeated lines due to mucosal injury risk. (Dose figures and this note are from Drugs.Wiki.)

    Tolerance

    Build-up develops over days to weeks of regular use
    Reset 3–7 days for acute; 1–3 weeks for full reset

    Tolerance Decay

    Full tolerance 2d Half tolerance 7d Baseline ~30d

    Based on general entactogen/stimulant patterns: acute tolerance develops within a session; partial tolerance persists days to weeks, decaying roughly over 2–6 weeks depending on use intensity, sleep, and nutrition.

    Tip: for quicker logging you can also add a Custom Unit in the app, e.g. common dose ~ 15 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.
