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.

A psychedelic phenethylamine and benzofuran that is very potent and has a long duration. Was briefly sold as “2C-B-FLY” in 2005/6 and has lead to multiple deaths.


It produces an array of extremely dose-sensitive psychedelic effects when administered. It was first synthesized in 1998 by Matthew Parker from DOB-FLY. Bromo-DragonFLY is extremely potent and produces unusually long effects which reportedly can last up to several days.

It is considered to have one-third the potency of LSD by weight, making it remarkably potent relative to the vast majority of psychedelics. Due to its high potency and unpredictable dose-response, many reports indicate that the effects of this substance may end up being overly difficult to use safely for those who are not already experienced with hallucinogens. Specifically, given that the dosage and duration of this substance have yet not been fully determined, users are advised to start at the lowest possible, intake only through the oral routes of administration, and never re-dose during any time throughout the experience.

Very little is known about the pharmacology, metabolism and toxicity about Bromo-DragonFLY in humans. It briefly gained popularity among research chemicals circa 2010 until several deaths occurred after the substance was accidentally mislabeled and sold as 2C-B-FLY, leading to its prohibition. Bromo-DragonFLY has never been documented as being sold on the street and has seemingly stopped production on research chemicals gray market.

Due to its novelty and extremely short history of human usage, all information related to the use of this compound should be received with extreme caution. It is strongly recommended that one use the utmost harm reduction practices if choosing to take this substance.




Bromo-DragonFLY is an atypical psychedelic phenethylamine which is closely analogous to DOB; it is the difuran analog to DOB, where it incorporates the methoxy groups bound to R2 and R5 of DOB into five member furan rings fused to the central benzene ring. Bromo-DragonFLY belongs to a group of phenethylamine derivatives referred to as the DragonFLY compounds, named for their insect-like appearance of two “wing-like” furan rings fused on the opposite sides of the central benzene ring. It is worth noting that the R-isomer of the molecule is considerably more active than the other and as such doses must be adjusted accordingly.

Pharmacological Effects

The hallucinogenic effect of bromo-DragonFLY is mediated by its agonist activity at the 5-HT2A serotonin receptor. Bromo-DragonFLY also has a high binding affinity for the 5-HT2B and 5-HT2C serotonin receptors, and is most accurately described as a non-subtype selective 5-HT2 agonist, as it is actually twice as potent an agonist for 5-HT2C receptors as for 5-HT2A, as well as being less than 5x selective for 5-HT2A over 5-HT2B. It is further suggested that Bromo-DragonFLY almost completely inhibits MAO-A activity, which makes itself unable to metabolize. This is probably the cause for an abnormal duration of action. However, the role of these interactions and how they result in the psychedelic experience continues to remain elusive.

Physical Effects

The physical effects of Bromo-DragonFLY are comparable to that of traditional phenethylamines such as 2C-B, mescaline and 2C-E.

Subjective Effects

Visual Effects




Bromo-DragonFLY visual geometry can be described as more similar in appearance to that of mescaline, 2C-B and 2C-D than psilocin or ayahuasca. It can be comprehensively described through its style variations as detailed in complexity, abstract in form, synthetic in style, structured in organization, brightly lit & multicoloured in scheme, glossy in shading, flat in edges, large in size, fast in speed, smooth in motion, angular in corners, non-immersive in depth and consistent in intensity. Bromo-DragonFLY has a contradictory combination of "naturalness", but also presents a "neon and digital" observation. At higher doses, users are significantly more likely to experience a state of Level 8B visual geometry over Level 8A.

Hallucinatory states

Bromo-DragonFLY produces a full range of high level hallucinatory states in a fashion that is comparable to mescaline or 2C-E. This is more consistent and reproducible than that of many other commonly used psychedelics such as 2C-B or LSD. It tends to occur at heavier doses and integrates seamlessly with the accompanying geometry. These effects generally include:
