Responsible Research with DCK

Always practice responsible research. You should read and educate yourself before undertaking research with any chemical. The Psychonaut Wiki has some very helpful resources and information on DCK

What is DCK?

2′-Oxo-PCM (also known as deschloroketamine, O-PCM, DXE, and DCK) is a lesser-known novel dissociative substance of the arylcyclohexylamine class that produces dissociative, anesthetic and hallucinogenic effects when administered. Other chemicals in this class include DMXE, 2-FDCK and 3-Me-PCPy.

DCK was one of the first ketamine analogues that appeared on the research chemical scene in the early 2010s. Many researchers experiment with it as a legal alternative to ketamine. However, the results achieved are substantially different. Notably, the duration of experiments with DCK tends to last several hours, compared to 30-60 minutes with ketamine or 2-FDCK.

Chemical Properties

Deschloroketamine, or 2-Phenyl-2-(methylamino)cyclohexanone, is classed as an arylcyclohexylamine drug. Arylcyclohexylamine drugs are named for their structures which include a cyclohexane ring bound to an aromatic ring along with an amine group. Descholoroketamine contains a phenyl ring bonded to a cyclohexane ring substituted with an oxo group (cyclohexanone). An amino methyl chain (-N-CH3) is bound to the adjacent alpha carbon (R2) of the cyclohexanone ring.

Descholoroketamine is a chiral molecule and is often produced as a racemate. Des- is a prefix used in chemistry to denote the absence of a functional group (in this case “chloro”) hence deschloroketamine is named for lacking a chlorine substitution on its phenyl ring, which is found in ketamine.

Pharmacological effects

Due to the lack of research regarding the substance, all discussion regarding the pharmacology of it is purely based on its structure and subjective effect similarities to other arylcyclohexylamine dissociatives such as 3-MeO-PCP, PCP and MXE. With this in mind, DCK is thought to act as an NMDA receptor antagonist. NMDA receptors, a type of glutamate receptor, allow for excitatory electrical signals to pass between neurons in the brain and spinal column; for the signals to pass, the receptor must be open. Dissociatives inactivate the NMDA receptors by blocking them. This disconnection of neurons leads to the general loss of bodily sensation, motor coordination, memory recall and eventually this substance’s equivalent of the “k-hole.”

Some of the most commonly reported effects are:

  • Spontaneous physical sensations
  • Motor control loss
  • Depersonalization
  • Dream potentiation
  • Creativity enhancement

Potential Side Effects

  • Nausea
  • Sedation
  • Decreased libido
  • Time distortion
  • Optical sliding


DCK is classified as illegal in:

  • Latvia
  • United Kingdom
  • Canada

  1. arturkarlik

    My feelings are mixed at this one. Very fun experience when combined with psychedelic, but rather boring on it´s own. I will definetly give another chance to this and I hope this was just a Bad batch

  2. CodeGeasUserName

    Very good. I really liked the high doses of 40-50mg

  3. samsarafugitive47

    for future customers just so you know, this is the tan/brown powder batch, speaking as of March 2024. haven’t had the chance to try previous batches, but even with little to no dissociative tolerance, 30mg IN resulted in only a portion of the supposed effects that this dose should cover. what little was present felt very cold, but kind of more wonky when compared to the lovely DMXE. might have to try a bit higher doses to discover the full potential. price, delivery and communication are perfect as always. thanks to the team, one love, much peace.

    • Axander

      this weird powder always make me nauseous :_D
      taste is reaaally weird

    This DCK is absolut TRASH, do not buy it, brown peace of shit.

    • Voitechus

      Why so? I do not think purity is the problem here but your expectations and ego are problerm here.

  6. uvechanged

    40mg insufflated – I’ve experienced smooth come up, a slightly euphoric and short peak, and a very long comedown. The lingering dissociation was unpleasant to me, and I couldn’t fall asleep 10 hours after dosing. During the peak, it reminded me of DMXE, just slightly cleaner and less euphoric. Overall I am not sure I want to dose again. I will probably just use up what I got and move on. I’ve read some benzo after peak can help with the longlasting comedown, but I didn’t have any at hand. Also, I got super nauseous during the comedown and had to lie down in darkness to prevent myself from vomiting. Worth a try, but far from my favorite disso.

    • Voitechus

      Good report but You obviously took too much for yourself. It is pretty heavy dosage. I personally did not had those unpleasent research. I also did not took more than 25mg at once. It reminded me DMXE too but different. It is less warm but much more racional than DMXE I would say. Both are great for introspection IN LOW DOSAGES.

      • uvechanged

        The other times I’ve dosed were much nicer in terms of side effects. I dosed about the same or more, but there was no lingering dissociation or nausea. Very short peak for me though. It’s still not my favorite, but I like it more now.

    Rats revealed occitoxyn production during and after test. The sample was high purity and longest duration and potent as is wellKnown analogue🧑‍🔬👍

  8. wdrs

    Good disso effects. Can’t compare with K, but definitely a good time in higher doses with 1V. No regrets. Recommended

  9. desintegrator

    My rats did not really like this substance. Reported almost no visuals, just felt dissociated and confused for a long time. Very hard to sleep afterwards and felt hungover the next day.

  10. jachyyy (verified owner)

    I did not really like this disso. Longer lasting than 2fdck, but colder and without that magic.

  11. MxM (verified owner)

    Deep, lasts long enough and has legs. “Magical” and cozy, for lazy Sunday afternoons. The downside is that it has some bodyload during and can be felt the whole next day, dizziness and pressure drops. Also it’s antibiotic properties isn’t just urban legend I could tell. I had it from two different sources on separate times. The one from here was brownish and I actually found the other batch to be superior. Still, no regrets

  12. Boaz08 (verified owner)

    Probably my favorite disso RC. Wish it was a bit cheaper, but sadly dissos get more and more expensive.

  13. Mirar (verified owner)

    Schöne Wirkung
    Hält lange und wirkt intensiver als 2 fdck

  14. W୩ (verified owner)

    Produit de qualité aux effets surprenants, dosage initial par voix direct à sous doser en premier lieux

  15. Jfraktal (verified owner)

    Le batch “Sandy Brown” est plus agréable à faire consommer à mes plantes, texture fine qui irrite moins les cellules.
    En spray c’est vraiment le top si vous n’êtes pas à domicile.

  16. Olivier Aubert

    Very bland K where’s the Magic? Gets you disso and that’s about it .. so disappointed compared to 2-FDCK

  17. Space Cooker (verified owner)

    Our research showed really interesting initial dissociative results. Our Guinea Pigs were able to clearly hole.
    Duration is a bit on the long side, so our test subjects were feeling a bit tired after some successive experiments.
    Top research Subject thx CC !

  19. barry (verified owner)

    I havent researched this for quite some time so Im not sure if it is normal for recent batches to lack the sand like texture but the test amount I received was more of I fine powder and i honestly found it to be better than before

  20. Diego

    Y lo mejor es que se siente mejor que la original

  21. Diego

    Me encanto la experiencia y volvere a probarla

  22. simonsterba10 (verified owner)

    It is maybe even as same interesting chemical as regular k.

  23. inmfast (verified owner)

  29. brazzer

    very potent and interesting dissociative. economic too

  30. Lyon

    Made my own nasal spray with this and works like an absolute charm it is a nice, warm and comfortable dissociative and I like that this is not as intense as other dissociatives

  31. Luca

    Good quality I always liked DCK the most. But i got a question when will there be a new ketamin for the german customers?

  32. Nilhuse721 (verified owner)

    I found it great for the price, i find it 2f like at high dosage ( starting 25mg ) BUT missing this magic i found in 2FDCK… This feel more cold but bright side make me sleep easy 🤣👍😴 anyway, big love team CC

  40. weisdtc707 (verified owner)

    At first i was not impressed with this chemical until during one of my science experiments i felt as if i had left my body and traveled to heaven i couldnt believe it. Amazing chemical, just dont do experiments with it too often.

  41. S

    Great product, took a couple weeks longer than normal to arrive but that’s kind of expected right now.
