Summary
MDMPEA is an obscure research compound patented by Merck in 1956 as an antitussive but never marketed clinically. Animal studies showed only moderate cough-suppression efficacy. It is classified as Schedule I in the USA as a positional isomer of MDA, prohibiting all non-research human use.

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 with moderate stimulation and sensory enhancement, low empathy
Strong euphoria and anxiety/jitters with mild stimulation, low focus
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.
Acute tachyphylaxis and post‑use depletion are plausible with repeated dosing in one session; multi‑day spacing is prudent. Data quality is low/anecdotal.
