Summary
N-Methyl-4,4'-difluoro-modafinil (also known as N-Methylbisfluoromodafinil, Dehydroxyfluorafinil, and Modafiendz) is an obscure nootropic of the benzhydryl class with no history of research. Although it is closely related on a structural level to adrafinil and modafinil, neither a pharmacological nor a safety-profile similarity should be assumed.

Import into PsychonautWiki Journal
The PsychonautWiki Journal app includes Dehydroxyfluorafinil, but its built-in data can be thinner than ours. Importing this file adds a separate "Dehydroxyfluorafinil (Substance Search)" custom substance with our dose ranges, durations and tolerance, so you can log against whichever you prefer.
Ranges are harm-reduction guidance, not a prescription.
Tolerance
Tolerance Decay
Acute tolerance: develops within a single session — the reset numbers above apply after sustained heavy use, not after one binge. Within-session tachyphylaxis usually resets largely overnight.
Patterns extrapolated from modafinil‑class anecdotal use; daily use for 1–2 weeks often blunts effects, with partial reversal after 3–5 days off and near‑baseline after 2–4 weeks. Data quality is anecdotal, individual variability is high.
