Psychedelic Research Chemicals or RC Chems are new synthetic substances which are structurally similar to the original drug, while being functional analogs. Data on their effects limited due as they’re fairly new and do not have a lot of human consumption history.
Psychedelics are substances (natural or laboratory made) which cause profound changes in a one’s perceptions of reality. While under the influence of hallucinogens, users might hallcuniate visually and auditorily.
Disclaimer: Psychedelic drugs offer some of the most powerful and intense psychological experiences. Additionally these substances are illegal in many places. We understand that even though these substances are illegal, their use occurs frequently. We do not condone breaking of the law. By providing accurate information about these substances, we encourage the user to make responsible decisions and practice harm reduction.

DOB is a relatively uncommon synthetic psychedelic. It is best known for its very low doses and long duration. Historically it has rarely been taken deliberately, but in place of LSD, however it has recently found its own place in the research chemical scene.
It is a member of the DOx family of psychedelic amphetamines. While DOB had first been synthesized in 1967 and briefly tested in 1971, it took until the 1991 publication of the book PiHKAL ("Phenethylamines I Have Known And Loved") by Alexander Shulgin to be documented in-depth. Today, DOB is used as a recreational drug and an entheogen.
It is still rarely sold online but is more commonly found in the streets the form of misrepresented LSD due to its ability to fit onto similar-sized blotter paper. Very little data exists about the pharmacological properties, metabolism, and toxicity of DOB in humans. Along with its sensitive dose-response, unusually long and unpredictable duration, many reports also suggest that this substance may be overly difficult to use safely for those who are not already very experienced with using hallucinogens.
It is highly advised to use harm reduction practices if using this substance.
Amphetamines are substituted phenethylamines containing a phenyl ring bound to an amino (NH2) group through an ethyl chain and a methyl group bound to the alpha carbon Rα.
DOB contains methoxy functional groups OCH3 attached to carbons R2 and R5 as well as a bromine atom attached to carbon R4 of the phenyl ring.
DOB is the amphetamine analogue of the phenethylamine 2C-B.

|DOB Duration Data|
- The 5-MeO class of tryptamines can be unpredictable in their interactions, particularly increasing the risk of unpleasant physical side effects.
- Cannabis has an unexpectedly strong and somewhat unpredictable synergy with psychedelics.
- As an NMDA antagonist MXE potentiates DOx which can be unpleasantly intense
- The combined stimulating effects of the two can be uncomfortable. Coming down on the MDMA while the DOx is still active can be quite anxiogenic.
- High doses of caffeine may cause anxiety which is less manageable when tripping, and since both are stimulating it may cause some physical discomfort.
- MAO-B inhibitors can increase the potency and duration of phenethylamines unpredictably
- The DOx class as psychedelic stimulants have the potential to mask the effects of DXM and could lead to redosing to an unsafe level. DXM can also potentiate DOx resulting in an unpleasantly intense experience.
- Details of this combination are not well understood but PCP generally interacts in an unpredictable manner.
- The combined stimulating effects of the two can lead to an uncomfortable body-load, while the focusing effects of amphetamine can easily lead to thought loops. Coming down from amphetamines while the DOx is still active can be quite anxiogenic.
- The combined stimulating effects of the two can lead to an uncomfortable body-load, while the focusing effects of cocaine can easily lead to thought loops. Coming down from cocaine while the DOx is still active can be quite anxiogenic
- Tramadol is well known to lower seizure threshold and psychedelics also cause occasional seizures.
- Drinking on stimulants is risky because the sedative effects of the alcohol are reduced, and these are what the body uses to gauge drunkenness. This typically leads to excessive drinking with greatly reduced inhibitions, high risk of liver damage and increased dehydration. They will also allow you to drink past a point where you might normally pass out, increasing the risk.
- No unexpected interactions.
The head space of DOB is described by many as one of prominent mental stimulation and a powerful enhancement of a person's current mental state. Many users report that it may not be as deep as other traditional psychedelics such as LSD or psilocin and that it is comparatively empty regarding its insightfulness.
- Anxiety & Paranoia
- Analysis enhancement
- Conceptual thinking
- Thought acceleration
- Thought connectivity
- Cognitive euphoria
- Analysis suppression
- Emotion enhancement
- Empathy, affection, and sociability enhancement - This component is inconsistently manifested only in the context of social settings in which one is within the company of others. These feelings of sociability, love and empathy are much weaker and less sharp than those found on substances such as MDMA and 2C-B, but still prove strong enough to provide therapeutic effects.
- Increased music appreciation
- Increased sense of humor
- Immersion enhancement
- Novelty enhancement
- Suggestibility enhancement
- Language suppression
- Memory suppression
- Ego death - While DOB is technically able to produce states of ego dissolution, it tends to more often than not develop only in extremely high doses, with grave physical and mental side effects being apparent and is often of a terrifying nature.
- Time distortion
- Thought loops
DOB’s psychedelic effects are believed to come from its efficacy at the 5-HT2 receptor family as a partial agonist. DOB appears to be quite selective for the 5-HT2B receptor and is often used in scientific research when studying the 5-HT2 receptor subfamily. It has been suggested that DOB is a prodrug metabolized in the lungs. However, the role of these interactions and how they result in the psychedelic experience continues to remain elusive.
- Stimulation - DOB is usually considered to be extremely stimulating at levels which do not become overwhelming and are encouraged instead of forced. This results in a shakiness and unsteadiness of the hands at high dosages, but encourages the person to move around, run, dance, climb and generally engage in physical activities. The level of stimulation varies between users with some people reporting it to be somewhat similar to amphetamine in its intensity and others reporting that it is extremely subtle even at higher dosages. In comparison, other more commonly used psychedelics such as psilocin are generally sedating and relaxed.
- Spontaneous bodily sensations - The "body high" of DOB is manifested as somewhat intense in comparison to most classical psychedelics such as LSD. The sensation itself can be described as a constantly present yet somewhat mild energetic pins and needles sensation that encompasses a person’s entire body. It is usually static in its position and felt over every square inch of the skin as if it was coming from behind the user's body. Occasionally, however, it manifests itself in the form of a continuously shifting tingling sensation that travels up and down the body in spontaneous waves.
- Physical euphoria - It should be noted that this effect is not as reliably induced as it is with substances like stimulants or entactogens, and can just as easily manifest as physical discomfort without any apparent reason. DOB and other psychedelic amphetamines tend to lean towards physical dysphoria more so than other psychedelics.
- Changes in felt bodily form
- Bodily control enhancement
- Tactile enhancement - Feelings of enhanced tactile sensation are consistently present at moderate levels throughout most DOB experiences.
- Stamina enhancement
- Bodily pressures
- Temperature regulation suppression
- Abnormal heartbeat
- Increased heart rate
- Increased blood pressure
- Increased perspiration
- Muscle contractions
- Muscle spasms
- Muscle cramps
- Difficulty urinating
- Nausea - Mild to extreme nausea is typically reported when consumed in moderate to high dosages and either passes once the user has vomited or gradually fades by itself as the peak sets in.
- Appetite suppression
- Stomach cramps
- Vasoconstriction - This effect is reported to be more common than with other psychedelics and can feel prominent and uncomfortable.
- Increased salivation
- Pupil dilation
- Teeth grinding
- Restless legs
- Synaesthesia - In its fullest manifestation, this is a very rare and non-reproducible effect. Increasing the dosage can increase the likelihood of this occurring but seems only to be a prominent part of the experience among those who are already predisposed to synaesthetic states.
Disclaimer: The effects listed below are cited from the Subjective Effect Index (SEI), which relies on assorted anecdotal reports and the personal experiences of PsychonautWiki contributors. As a result, they should be taken with a healthy amount of skepticism. It is worth noting that these effects will not necessarily occur in a consistent or reliable manner, although higher doses (common+) are more likely to induce the full spectrum of reported effects. Likewise, adverse effects become much more likely on higher doses and may include serious injury or death.
- Drifting (melting, flowing, breathing and morphing) - In comparison to other psychedelics, this effect can be described as highly detailed, slow and smooth in motion, static in appearance and unrealistic/cartoon-like in style.
- Colour shifting
- Depth perception distortions
- Perspective distortions
- Symmetrical texture repetition
- After images
- Brightness alteration
DOB visual geometry can be described as more similar in appearance to that of LSD, 25I-NBOMe or 2C-B than that of mescaline, psilocin or DMT. It can be comprehensively described through its variations as intricate in complexity, algorithmic in form, synthetic in feel, brightly lit, multicoloured in scheme, glossy in shading, sharp in edges, large in size, fast in speed, smooth in motion, equally rounded and angular in its corners, non-immersive in-depth and consistent in intensity. Higher dosages are significantly more likely to result in states of Level 8A visual geometry over Level 8B.
DOB and other substituted amphetamines produce a full range of high-level hallucinatory states in a fashion that is more or less consistent and reproducible than that of many other commonly used psychedelics. These effects include:
- Internal hallucination (autonomous entities; settings, sceneries, and landscapes; perspective hallucinations and scenarios and plots) - In comparison to other psychedelics such as LSD, DOB is extremely high in internal hallucinations when approaching higher dosages. They are more common within dark environments and can be comprehensibly described through its variations as lucid in believability, interactive in style, new experiences in content, autonomous in controllability, geometry-based in style and almost exclusively of a personal, religious, spiritual, science-fiction, fantasy, surreal, nonsensical or transcendental nature in their overall theme.
- External hallucinations - These are often present during the comedown and can include shadow people, among other indescribable beings. These external hallucinations are often lucid, interactive, autonomous, and robust. As sleep deprivation and stimulant psychosis surface, a trip sitter should accompany individuals sensitive to stimulants for the last part of the comedown. The visual effects of psychosis have been reported to blend into the psychedelic visuals around the 16-24 hour mark, sometimes accompanied by auditory hallucinations.
Internationally, DOB is a Schedule I drug under the Convention on Psychotropic Substances.
