    Summary dose.wiki

    DPP-26 is the sulfone analogue of dipipanone, structurally related to IC-26 (methiodone, the sulfone analogue of methadone). Early user reports describe it as having faster onset and shorter duration than methadone, with notable euphoria. Vendor specifications and limited reports suggest approximately 0.4x morphine potency (roughly 25 mg DPP-26 equivalent to 10 mg morphine).

    Dose Information dose.wiki Drugs.Wiki

    Dose basis. The dose figures on this page are not clinical data. They are aggregated from community reports by a secondary source whose own notes state there is no human pharmacokinetic study behind them, and our internal audit flags this substance's dosing as unverifiable. Treat them as a rough orientation, not a safe range. Assume full respiratory depression, keep naloxone to hand, never dose alone, and never combine with benzodiazepines, alcohol or other depressants.

    The PsychonautWiki Journal logging app doesn't include every substance. To track DPP-26 there, start adding an ingestion, search for the name, and choose to add it as a custom substance. Paste these values:

    Description 
    DPP-26
Source: SubstanceSearch (substancesearch.com)

Oral dose (mg): threshold 5 · light 5-15 · common 15-35 · strong 35-60 · heavy 60+
Insufflated dose (mg): threshold 3 · light 3-10 · common 10-25 · strong 25-45 · heavy 45+

Oral duration: onset 20-45m · come-up 0.5-1h · peak 1-3h · offset 4-6h · total 5.83-10.75h · after-effects 12h
Insufflated duration: onset 5-15m · come-up 15-30m · peak 1-3h · offset 3-5h · total 4.33-8.75h · after-effects 8h

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 ~ 25 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 within days of regular use; analgesic tolerance faster than respiratory depression tolerance
    Reset 7–14 days for partial reset; full reset may take weeks — tolerance loss greatly increases overdose risk

    Tolerance Decay

    Full tolerance 7d Half tolerance 7d Baseline ~35d

    Patterns inferred from user accounts and general opioid pharmacology: daily use for a week commonly produces noticeable tolerance; partial decay occurs over 3–5 days; near‑baseline often requires 2–4 weeks. Cross‑tolerance with other opioids is expected.
