PCP and the relatives of the family do NOT make anybody superhuman. They do however anaesthetize and render the subject rather insensible to pain, thus they may struggle harder if assaulted, but they would in no sense be superhuman and the mythology about the drug is a bunch of utter claptrap of the most inane and profligate degree.
Whilst PCP itself has thus far not been an experience I have had, I have had various extremely close mimics of it. 4-methoxy-PCP (methoxy on the phenyl ring, substitution on cyclohexyl kills activity dramatically.) substitution position of a methoxy group moved to the 3-position (more stimulating, lowers seizure threshold, overdoses can induce one, and sufficient doses to produce desirable effects without overreaching the bounds of its safety margin are in my opinion perhaps less favourable than the 4-MeO isomer.)
3-hydroxyl is outstanding. As is the 2-oxo-3-methoxy-eticyclidone analog (methoxetamine, in the parlance of the street, and for short), being the analog replacing the piperidine ring with a methyl and adding a that oxygen in the 2-position makes it a kind of hybrid, of the shorter acting (due to the greater polarity to an extent, and acting as a kind of metabolic handle I believe should occur, a site of metabolic attack facilitating more rapid excretion and thus less residence time in the bladder than ketamine (the metabolite of K, norketamine can cause a severe ulcerative cystitis in those who engage in severe habits. Having it attacked on the ring will decrease the quantity converted to norketamine, or rather, the corresponding metabolite, presumably either changed to the hydroxyl and conjugated with sulfate, glutathione et cetera.)
Deschloroketamine being somewhat weaker. But of similar qualities.
They incoordinate, although ketamine, methoxetamine, deschloroketamine inebriate in a similar way to the phencyclidine (PCP) resembling them also are often possessed of a greater or lesser degree of potency, in addition to antagonist effects at NMDA glutamate receptors, which is the primary mechanism responsible for the sedative, anaesthetic, anxiolytic, anti-addiction (in many respects but its own, and I doubt to alcohol, although this is possible to likely, although I have never given myself an ethanol physical dependency in order to test it, it would be too dangerous and utterly unpleasant, both in the aquisition of the dependency, its temporary maintainance and its removal, but NMDA antagonists dramatically lessen and help block further aquisition of tolerance and physical dependency in response to opioid withdrawal from Mu-opioid receptor agonists, such as heroin, morphine, oxy, hydrocodone, codeine, et cetera. they also alleviate physical withdrawal from the drug class, and they help block aquisition of tolerance to psychostimulants. Not sure about dopamine reuptake inhibitor stimulants such as methylphenidate/ritalin or triple reuptake inhibitors. Never done a serious controlle study and took numbers. And I am not entirely sure I could provoke a psychological stimulant addiction if I tried. There are some quite powerful dopamine transporter blockers in the family though, making them primarily stimulant. Which is why those arylcyclohexylamine dissociatives closest to PCP (the benzothiophene ring structure in place of the phenyl ring (there doesn't seem much steric tolerance in the NMDA receptor PCP binding site for this class of drug, wherever in the NMDA receptor ion channel (its a ligand and partially voltage gated receptor type, at resting potential its blocked weakly by the magnesium cation that occupies it at resting potential, when activate at need by glutamate or aspartate (aspartate binds at the orthosteric, glutamate binding site, although appears to function as a partial competitive agonist)
Whether or not he WAS on the stuff it doesn't make a fucking bit of difference. If the guy was a dick, he'd be a dick if he got pissed on lager. All it would take is for him to get stressed or over the top enough to unleash his inner dick, with or without additional help. Hell an average two legged meatsack can do that to another if they so decide if they possess the vestiges of both will to do so an the intellect to realize how the deed were to be performed in the material sense.
