Let me start tis off by saying I have a HUGE dissociative tolerance...Also, I have pushed the limits several other times in the past. Some notables are (all seperate experiences) 4g DXM ate, 1g K snorted, 500mg MXE ate...Humbled myself each time, but this is bout 3-MeO-PCP.
By this point, I had prolly used 1g of 3-M-P in a month's time, maybe 20-40mg bumps or 10-20mg shots. I lost what was left of my latest 1/4g, and for a week or so, I had to go completely sober (as I spent last of my cash on the 3MP). Then, I found it under the couch, guess I got high and hid it. Now, I usually don't realy "crave" dissociatives, I mean, their my preferred class and if around I'll use regardless of what else is going on in my life, but not having them, even for extended periods o time usually don't weigh on me. But I knew I had several doses left, just didn't know where, and I decided that when I found it, I was just going to say fuck conservation, IV it all. So I weigh it out, roughly 80mg, my scale is off by +/- 3mg, and I had second thoughts. But, ya know, what can I say, I like uncomfortably intense trips. Banged the 80mg, then laid back. Comeon almost felt like an opiate, very down. Visually, everything had a reddish glow, as if I were wearing rose-tinted glasses (I know, so cliche). It was legitimately psychedelic, which surprised the fuck out this dissociative "veteran"...I mean, had always been visual, but now there were fractals, colorshifting, looking at my face I saw different people flash it, not your "normal" dissoc. visual effects. No hole at all, not even close. Very much in my surroundings and body, which felt like it was made of marshmallow cream. I was so convinced of the idea, I actually took a razor to my arm to check it out, nope, but defintely not thinking rationally. Called a friend, she said I was slurring and talking so slow she couldn't follow. Timed me once, took me a full 4 1/2 minutes to say a complete sentence. I got "stuck" for several hours, couldn't even work a remote, much less get up off the couch. Very euphoric, absolutely no sinister edge, though I generally didn't think at all. Maybe lasted about 14hrs, might have slept during some of it, don't remember much.
As for preferred ROAs, I like to shoot shit, but isn't a lot of use with 3-MeO-PCP. Once I swear it bound to the receptor, was high maybe 5 minutes, then it got knocked off or something, baseline. No real rush anyway, duration doesn't really seem affected much though comeup is, dosage is maybe 2x oral so conservation of product not really a big deal. Oral or SL, hate those ROAs for anything, only really use them if there is no other way, or if others are too inconvenient, but after snorting this shit all night and having to work in the morning, I found a small finger-dip or dump a bit under my tongue (eyed, can't take scale to work) kept me going. Snorting might be my fave, relatively easy, can be done most places discreetly. I must say, there was something special to rectal, like provided a different trip only accessible by this method.
