Never tried straight PCP but tried 3-MeO, 3-HO and PCE variants. 3-MeO is supposed to be the closest and feels like a more nitrous-like and very stimulating dissociative compared to ketamine. Think a NDRI/Dopamine agonist feeling over a NDRA feeling but still its own flavor of stimulation. Feels a bit serotonergic as well on the comedown/afterglow.
High doses feel like overamping while being on a constant double-balloon of nitrous barely being able to move yet thrashing around like a maniac and speaking incoherently. The longer youre on it the more alien/chaotic/manic your thought process and behavior becomes.
