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 on 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

Escribo mi reseña en español para poder expresarme con total claridad, ya que mi nivel de inglés no es muy alto. Para comenzar el servicio fue perfecto. Tardó en llegarme a Alcalá de Henares (España) tan solo 1 semana desde que realicé el pedido. La experiencia con el producto fantástica. Soy un psiconauta relativamente experto, pero es la primera vez que accedo a este tipo de productos a través de gente profesional. El viaje fue un Océano de sensaciones y percepciones únicos y maravillosos, el cual compartí con mi pareja. Nos adentramos en el bosque mientras el ácido iba haciendo su efecto sobre nosotros, resultando en una conexión extrema y placentera con la naturaleza, así como con mi compañera de viaje. Pienso repetir y volver a confiar en Chemical Collective, además de experimentar con otros productos de su catálogo

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

1 month ago

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.

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

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

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.

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

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

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

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.

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 !

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
