O-PCP

                                       

Age: 30

Weight: 150 lbs

Dosage: 175 mg intransal

Setting: At home. Late at night.

 

[NOTE: This is an extremely large dose! Don’t do this! The purpose of this report was to induce an intense experience to analyze the full character of the drug. Casual recreational use should not seek to replicate this. For dosage guidelines for this compound I would recommend people start in the 10-20 mg range, as it is certainly active down there. There is a long plateau on its effects past that, but an experience similar to mine would probably manifest around 80-100mg for a dissociative naïve user.]

 

They said it couldn’t be done. O-PCP was always a fantasized about compound- a pretty obvious design, mixing and matching components from some of the most popular dissociatives out there. In the lab where I had worked it had been a fabled puzzle, a tricky and fickle synthesis condemned to forever be a backburner project. It’s first official appearance was on a patent by Gilgamesh pharmaceuticals, as part of their vast swath of 2’-Oxo-Arylcyclohexylamines. We struggled with synthesizing but my colleague devised a new route (publishing pending) and successfully made it after some trial and error!

Enter 2025- It is being offered from one of the world’s most prominent ACH labs. I do not know their synthetic route but they seem to have locked down a process to produce it in great bulk. The miracles of modern science and engineering! The batch that entered the world curiously and unfortunately took on a contaminant that made it smell and taste exactly like garlic powder. Running NMR, I was never able to puzzle out the specific contaminant. It was suspected DMSO but there wasn’t any noticeable contamination from that. The lab lost access to GCMS so I wasn’t able to try and puzzle it out that way. A shame. But O-PCP does not inherently have a garlicy odor, a reference sample my colleague synthesized and tested as analytically pure did not bear it. Recrystallizing in ethanol did largely remove the odor.

Garlic flavors aside, this is a very odd compound. I would liken it most to MXPr- fairly lackluster on its own but it really shines in combination with other compounds. I would define it primarily by stillness- it is a static dissociation, most it does is rain dissociative energy down around oneself in a perfect square at a steady rate, every drop falling at a perfect 90 degree angle to the floor. Alone, it is a dull, metallic, front of the head sort of dissociation, something there but a hint of something more to come out later, but then it never comes. I can feel it a bit in my extremities, I can feel it in my heavy and disproportionate head, but there is no rush or compulsion after that. This drug does not lend itself to rushes or compulsions, not to desires to drives. It just sits there, perfectly still, legs crossed. Perhaps a little bit of mania is flitting through my mind at this time too.

When combined however, it glows and blossoms and comes alive, a golden warm flower that latches on to any experience to offer a rich, heavy, bright, energetic, vibrant dissociation- a veritable rainbow furnace of warm burning gravitous energy. It adds a pleasant meldable depth to anything else- opioids, alcohol, benzos, other GABAergics- but particularly gabapentanoids (pregabalin, gabapentin) and other dissociatives. This is an excellent mixer drug if you want a cynical swirling sweeping dancing confident bright gold edge mixed into an experience with appreciable dissociative heft and floppy pleasurable weight. It’s a pleasant and unique body feel all around.

Sorry it took me so long to report on this one, it’s been around since June. It was really hard to lock down its exact nature and it took a lot of trials to reach a point where I could confidently summarize it and address its multitudes. A lot of people have written this one off as being boring or unfulfilling but I think there is a ton of depth to it if used properly.

This report covers an experience with an extremely high dose that is modulated by cannabis. This one is also interesting in that it can present noticeable effects as low as 10-20 mg for some users. It can be pushed upwards pretty far and seems to plateau out after a point in big doses. A 10-50 mg dose is a pleasant warm stimulating threshold with a bit of mania. The 50-120 mg dose range feels generally the same with the qualities described in this report. Beyond that it can be more intense and unique. These doses must also account for my tolerance. The disclaimer in the beginning has my notes on how one should navigate that.

 

T0:00- dose taken, stings a little, smells strongly of garlic powder. Literal garlic powder.

 

T0:10- Feels like my head is inflating.

 

T0:15- Feeling more and more lightheaded, my head is simultaneously heavy and floaty like it is being inflated, a bit of a stimulating rushing undercurrent. Sensations are mostly focused on my forehead above my eyes and behind my eyes. Sounds seem more staccato and abrasive and jarring. Head feels heavy. I am watching king of the hill with my spouse and reading about paint samples online. There is a little bit of a manic and curious push that makes me want to read all of these mundane things. My spouse notes I am slurring my speech and walking less steadily on my feet.

 

T0:45- I am alone now. The same sorts of dissociation have been building, I am being cushioned on all sides by walls of static. I don’t feel a compulsion towards any particular activity. I am still mostly functional, I can read and type and get up and drink water. It’s a weird buzzing in the background.

 

T1:23- There is a heavy dissociation focused on my head, with my body mostly an afterthought. I still retain full motor skills. It still just feels dull and distant. There’s something there but it feels caged in and desaturated. I know how I can unleash the beast, so to speak- I take a large hit of cannabis from my gravity bong.

After returning  to my room, the gears begin to turn into overdrive. I feel my fingertips going completely numb, one joint at a time, each knuckle glowing standing hot bright white and then blipping out to a still numbness. The open eyed visuals pulse breaking the world into a mosaic of interlocking cells- every object in my surroundings collapses and is divided into a various rectangular zones defined along lines of contrast, that pulse with golden and orange metallic flashes. These are all arranged and interlocked and encapsulating my field of vision, it is almost a vision with compound eyes, each cell a still, solid rectangle. The borders of these cells flow with gold and raspberry twine colors. Bright and energetic. Everything is drifting. Everything is adorned in gold, I am a stoic and still King Midas, gilding the spaces before me.

I seek to enter a hole, I plug in my headphones and listen to some chiptune- Supergalactic by IAYD. Lots of satisfying beeps and bops to play off the golden reflected light. I lay down on my couch and can feel my body go numb, turn to metal with chipped red paint, and lay still, and still and still.

The hole was beautiful, it was smooth, everything felt metallic tinged and there were neon pulses of every warm color, particularly those oranges and deep golden yellows. One notable thing though was there was no motion- many times in a hole with music as a synesthetic experience, I can feel sensations of my body being pushed, pulled, flipped, floated, spun etc; in response to these internal hallucinated projections. There was no such feeling with this one. I was a still body. I didn’t feel my body, I had no proprioception, but everything was still. I was just bathing in a pool of liquid gold, the surface a mirror pulled taught by immense surface tension that threatens to crack at any moment, sending off golden fireworks to the sky. There were no compulsions in virtual motion in this space, there were no pull or directions or flights, no push or pulse, just me, still, the inner world of the hole happening around me. It was bizarre to feel after a point. It is a golden lazy river.

I am fully lucid and able to think clearly. The headspace is one of energized mania. As the gilded scenes dance around me I am fantasizing, I am fantasizing about the impact of my life, about how many people I have affected over my life, over how I would navigate what feels like in inevitable confrontation with the forces of the state. It’s all very solipsistic and self indulgent. And even in its intensity it is still and muted, it’s a mania for brainstorming, not a mania for acting. I don’t feel any compulsion to engage in any activity or pursue any fantasy from my thoughts racing meditation session.

 

T2:00- The heavy physicality is starting to wear off at this point. I right myself and just engage in reading stuff on my computer. I am reading about George Stellar and his great cold northern expedition. I feel a lot of manic energy, but it is just searing in my head, it is not like so many of my familiar 3-MeO-substituted arylcyclohexylamines where the manic push runs downs my nerves and my bones- here it is just confined to my head, confined to my forehead and behind my eyes. Running in circles confined to a pen. The rest of the body is still, dead still and quiet.

There are still bright golden and orange visuals pulsing in cellular patterns as they were before. Everything is quiet and lingering. It’s all neutral. There’s no drive to do or pursue anything, I am blank. No motion, no compulsions.

 

T2:10- Reading about Slavic paganism, reading was difficult before when I was coming up, it’s all more coherent now. Typical manic dissociative comedown reading focus and intense curiosity and association.

 

T2:20- Extremities still almost completely numb, still a tightness around my forehead, but otherwise I feel mostly normal. Not particularly manic or stimulated anymore, just kinda there. I am tired and bored.

 

T2:40- Pretty steadily coming down. Physical sensations are fading.

 

T3:00- A bit of lingering stiffness behind my eyes. Maybe a little bit of stimulation.

 

T4:00- Back to baseline. Go to sleep.

 

Conclusion: O-PCP is, at reasonable doses, very boring on its own. It reminds me of MXPr in that regard. It sits in the background, it doesn’t assert itself. It needs friends to be brought out of its shell. I have loved this drug purely as a mixer. It mixes beautifully with pregabalin. It mixes beautifully with manic stimulating dissociatives. It blends wonderfully with ketamine. It’s cozy with Carisoprodol or some oxys. Use it like a spice, to add heaviness and warm bright visuals to an experience. There is a gently flowing motion of it like a lazy river adorned with ornate golden floats that can seep into other experiences. It’s good for just sitting still. I like it for playing strategy games, it makes me feel more immersed. It might not be the most dancey but one can always try. It is a really odd and very unique compound that has little of its own definition, but a lot of heft when combined with other things.
