Summary
PCE is a potent dissociative that causes psychosis and mania at significantly higher rates than other dissociatives. Users should avoid taking the drug multiple days in a row or in high doses. Volumetric liquid dosing is strongly recommended due to the drug's extreme potency, as most standard milligram scales cannot accurately weigh doses below 10-15 mg.

Effects
Aggregated from 3 single-substance Erowid experience reports
Each bar shows the share of analyzed reports whose text mentions that effect — a mention is not always a first-hand experience (fear of an effect or something witnessed can count). Mentions saying the effect did not happen are left out; that check reads keywords, so it can miss some. The shaded band on a bar, and the small range after its number, is the 95% interval: where the share could plausibly be with other reports of the same kind. Fewer reports, wider band. Tap or hover any number for details. The second value is the Bluelight extractor's per-effect confidence; a dash means the row is Erowid-derived, which has no confidence measurement.
Too few reports for bars: these effects come from 3 single-substance Erowid reports, and a bar is drawn only from 20 reports or more. With fewer, a percentage cannot tell a common effect from a rare one. Counts are shown instead. Why 20?

I t's very similar to PCP. I usually synthesize my drugs myself, can't get the precoursers for PCP, but I can easily get them for PCE, so I thought "close enough" and went with that.
The addiction to dissociative drugs is very strange. I've tried many drugs before PCE, which are Mephedrone, Methcathinone, Methamphetamine, benzos and some barbiturates, tramadol and probably a few others.

Age: 26 Weight: 130 lbs Dosage: 15 mg intranasal Setting: My house Here is an overall summary of this drug that I wrote. This is a detailed report of a single experience. Preface: The design for 3-Me-PCE is a straightforward low-risk bet for an active arylcyclohexylamine.
[Retrospective note: This report was written while partially under the influence. PCE most definitely has an ego-inflating aspect. Please keep this in mind while reading my somewhat self-loving report.] It is truly unfortunate that there is so little information available on Arylcyclohexamines, as somewhere between Ket...
This is basically Tiletamine with a phenyl instead of a thienyl ring. I got the chance to try this one. I was *extremely* excited as it is the closest we have to a Ketamine analogue (but still very far)...
