Aliases: 3,4-dmohp, 3,4-dimethoxy-ฮฑ-php
Summary
Extremely limited human data. All dosage and duration figures are extrapolated from user reports and close structural analogues (ฮฑ-PHP, ฮฑ-PVP, MDPV). Functions as a potent dopamine and norepinephrine transporter inhibitor; serotonin activity appears minimal.

Effect Profile
Scores (1–10) curated from multiple sources:
- Effect keyword matching from PsychonautWiki catalog
- Weighted by importance: core (×3), major (×2), minor (×1)
Strong euphoria and anxiety/jitters with moderate focus, low stimulation
Tolerance
Tolerance Decay
Acute tolerance: develops within a single session โ the reset numbers above apply after sustained heavy use, not after one binge. Within-session tachyphylaxis usually resets largely overnight.
Tolerance appears to build rapidly over multiโday use (as with ฮฑโPVP/MDPV) and decays over weeks; figures are approximate and based on patterns reported for structurally similar pyrrolidinophenones rather than controlled studies. Space sessions by multiple weeks to limit escalation and psychosis risk.
