A quite potent fentanyl analogue.
Dose Information
Dose basis. TripSit is the only source for these figures and states three tiers ending in an open "Strong: 1.5 mg and above" โ there is no Heavy band and no established ceiling. The numbers are compiled from user reports rather than measured, on a fentanyl analogue where the difference between tiers is a fraction of a milligram.
| ROA | Light | Common | Strong | Heavy |
|---|---|---|---|---|
| Oral | 0.25-0.5mg | 0.5-1.5mg | 1.5mg+ | - |

Add to PsychonautWiki Journal
The PsychonautWiki Journal logging app doesn't include every substance. To track Methoxyacetyl-Fentanyl there, start adding an ingestion, search for the name, and choose to add it as a custom substance. Paste these values:
Methoxyacetyl-Fentanyl Source: SubstanceSearch (substancesearch.com) Oral dose (mg): light 0.25-0.5 ยท common 0.5-1.5 ยท strong 1.5+ Oral duration: after-effects 1-4h 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 ~ 1 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
