O-PCE (2′-Oxo-PCE or Deschloro-N-ethyl-ketamine) in crystal form is an extremely potent synthetic dissociative of the arylcyclohexylamine class. It is a structural analog of Eticyclidine (PCE) and Ketamine, but it is widely considered one of the strongest and longest-lasting dissociatives available in the 2026 research chemical market.
Effects and Duration
Unlike ketamine, which is known for its “short trip,” O-PCE is a marathon substance.
| Feature | O-PCE Experience |
| Onset | 10–20 minutes (nasal); 30–60 minutes (oral). |
| Peak Duration | 3 to 6 hours (compared to 45 mins for ketamine). |
| Residual Effects | Total “after-effects” can last 12 to 24 hours, characterized by significant mental fog, motor impairment, and “grogginess.” |
| The “Hole” | The O-PCE “hole” is described as deeper, more clinical, and more physically “heavy” than a K-hole, often resulting in complete immobility. |
Potency & “The Dosage Trap”
O-PCE is vastly more potent than ketamine, which leads to frequent accidental overdoses when users treat it as a direct substitute.
-
Potency Comparison: O-PCE is estimated to be 5 to 10 times more potent than ketamine.
-
Dosage (2026 Guidelines): * Threshold: 3–5 mg
-
Standard: 10–20 mg
-
Heavy: 25 mg+ (Highly likely to cause a total “blackout” or medical emergency).
-
-
Crystal Appearance: It often appears as large, clear, or white “shards” that can easily be mistaken for methamphetamine or MDMA. This has led to “drug alerts” in 2025 and 2026 where O-PCE was accidentally sold as a stimulant
