Methoxetamine (MXE)
Dissociatives
Methoxetamine (MXE) was the 2010s' most beloved research chemical — a ketamine analog designed to be longer, stronger and (many hoped) bladder-friendlier. For a few golden years it ruled the gray market; then China banned it and it nearly vanished.
Ketamine vs Methoxetamine — side by side
| Ketamine | Methoxetamine | |
|---|---|---|
| What it is | The original arylcyclohexylamine | 3-MeO-2-Oxo-PCE — ketamine with a methoxy group and ethylamine tail |
| Duration | 45–90 min | 3–6 h — 3–4x longer |
| Potency | Baseline | Stronger per mg |
| The 'feel' | Floaty dissociation, K-hole at high dose | Deeper, warmer, more euphoric by many reports; 'hole' is longer and more immersive |
| Bladder question | Chronic use destroys bladder lining (ulcerative cystitis) | Designed partly to reduce this — evidence never materialized; long duration means more exposure per session |
| Era | 1970–present | ~2010–2015 golden age, then bans |
| Current availability | Global | Rare — mostly gone since Chinese scheduling |
The verdict
MXE was the one RC that users mourned. It delivered a longer, warmer ketamine experience at a time when ketamine itself was scarce in some markets. The bladder-sparing theory never got its trial, and the drug's disappearance means it never will. Modern successor RCs (2F-DCK, DCK) chase the same crown with less charm. Ketamine remains the available, studied option — and its bladder damage is the reason chronic use is a real medical emergency.
?Frequently asked questions
Is MXE still available?
Rarely. Chinese scheduling in 2015 eliminated the main supply, and most 'MXE' sold since is other dissociatives mislabeled. It's remembered as the RC that disappeared mid-legend.
Was MXE safer than ketamine?
Unknown — that was the hope, never proven. Its longer duration arguably increases total bladder exposure per binge even if per-molecule toxicity is lower.
