Administration of 0.1 mg/kg IV of PCP produces a predictable series of mental alterations that can be difficult to differentiate from true schizophrenia. These effects may include defective perceptual discrimination, concrete thinking, psychomotor retardation, distractibility, alteration of body image, loss of body boundaries, and a profound sense of unreality. LSD, on the other hand, more closely simulates the secondary symptoms of schizophrenia, such as hallucinations.
So that's about 7-8mg, for an average size male. I guess the bioavailability can't be that much higher IV than insufflated, so the only difference really would be the rapidity of onset. I'd take that quote with a pinch of salt (or dust), it's not so bad!
Edit: But that report from 3.5mg (of what sounds like really impure PCP - looked like hash!?) sounds a lot stronger than I've had from 7-8mg insufflated in one go, or 15mg over a couple of hours, so I dunno!
Never had PCP cos it's just not around anywhere in the UK but have IV'd 3-MeO-PCP a few times and that is reportedly fairly similar. I loved the 3-MeO version (5-10mg range IV'd for me from memory) and would certainly be tempted should the ever-elusive PCP itself become available. Have also IM'd 3-MeO-PCE which was very enjoyable too.

Is 3-MeO euphoric and worthwhile? Or is it just "strange"? And do you know if it would interact with SSRI's at all? According to Bluelight, ketamine is safe while on SSRI's, but DXM is potentially lethal. Where would a PCP analogue fit on this scale? And did you notice any "hangover" effects? Tired? Anxiety? Depressed?

Now, correct me if I'm wrong (which I may be) but isn't the bioavailability the amount of drug which is metabolized? If that's the case then IV'ing would increase the potency as well as the speed of onset. correct?
^DXM is dangerous to use with SSRIs not because it's an NMDA antagonist, but because it's also a serotonin releaser.
