4-MeO-PCP crystals – More information
The synthesis of 4-MeO-PCP was first reported in 1965 by the Parke-Davis medicinal chemist Victor Maddox. A 1999 review published by a chemist using the pseudonym John Q. Beagle suggested the potency of 4-MeO-PCP in man was reduced relative to PCP. Two years later, Beagle published a detailed description of the synthesis and qualitative effects of 4-MeO-PCP which he said possessed 70% of the potency of PCP.
4-MeO-PCP was the first arylcyclohexylamine research chemical to be sold online. It was introduced in late 2008 by a company trading under the name CBAY and was followed by several related compounds such as 3-MeO-PCP and Methoxetamine (MXE).

4-MeO-PCP, or 4-Methoxyphencyclidine, is a synthetic dissociative of the arylcyclohexylamine class. 4-MeO-PCP contains cyclohexane, a six member saturated ring, bonded to two additional rings at R1. One of these rings is a piperidine ring (a nitrogenous six member ring) bonded at its nitrogen group. The other ring is an aromatic phenyl ring substituted at R4 with a methoxy group. 4-MeO-PCP is a PCP derivative, and structurally analogous to 3-MeO-PCP.
Potentially dangerous interactions
Although many psychoactive substances are reasonably safe to use on their own, they can quickly become dangerous or even life-threatening when taken with other substances. The following lists some known dangerous combinations, but cannot be guaranteed to include all of them. Independent research should always be conducted to ensure that a combination of two or more substances is safe to consume. Some interactions listed have been sourced from TripSit.
The toxicity and long-term health effects of recreational 4-MeO-PCP use do not seem to have been studied in any scientific context and the exact toxic dosage is unknown. This is because 4-MeO-PCP has very little history of human usage. Anecdotal evidence from people who have tried 4-MeO-PCP within the community suggest that there do not seem to be any negative health effects attributed to simply trying this drug at low to moderate doses by itself and using it sparingly (but nothing can be completely guaranteed). Independent research should always be done to ensure that a combination of two or more substances is safe before consumption.
It is strongly recommended that one use harm reduction practices when using this drug.
As with other NMDA receptor antagonists, the chronic use of 4-MeO-PCP can be considered moderately addictive with a high potential for abuse and is capable of causing psychological dependence among certain users. When addiction has developed, cravings and withdrawal effects may occur if a person suddenly stops their usage.
Tolerance to many of the effects of 4-MeO-PCP develops with prolonged and repeated use. This results in users having to administer increasingly large doses to achieve the same effects. After that, it takes about 3 – 7 days for the tolerance to be reduced to half and 1 – 2 weeks to be back at baseline (in the absence of further consumption). 4-MeO-PCP presents cross-tolerance with all dissociatives, meaning that after the consumption of 4-MeO-PCP all dissociatives will have a reduced effect.
Urinary tract effects
In terms of its long-term health effects when used repeatedly and with excess for extended periods of time, 4-MeO-PCP seems to exhibit almost identical bladder and urinary tract problems to those found within ketamine but to a lesser extent. This is because 4-MeO-PCP is a little more potent than ketamine, meaning that less of the drug needs to be consumed. Symptoms of ketamine-induced cystitis can become extremely serious and can be described as:
All of these, however, can easily be avoided by simply not using 4-MeO-PCP on a daily or even weekly basis and manually limiting one’s usage of the substance.
