Where to buy 2C-B-FLY for sale online

The proliferation of research chemicals in the market has given rise to many sellers and vendors, including those offering 2C-B-FLY, a designer drug with psychedelic properties. While scientists and researchers need to access such compounds for legitimate studies, the online marketplace for these substances remains a double-edged sword.
One of the significant advantages of buying 2C-B-FLY from online vendors is convenience. Researchers can access various research chemicals with just a few clicks. However, the ease of purchase often comes at the cost of quality and safety. The unregulated nature of the market means that not all sellers can be trusted.
It’s critical to exercise caution when choosing a seller for 2C-B-FLY or any other research chemical. Not all vendors adhere to strict quality control standards, potentially jeopardizing the integrity and reliability of scientific studies. Researchers must seek reputable sellers with detailed product information, including purity levels, batch testing results, and safety precautions.
Moreover, the legality of 2C-B-FLY varies from one region to another. Purchasing this designer drug without knowing local regulations can lead to legal consequences. Responsible vendors should provide clear guidance on the legal status of their products in different jurisdictions to ensure researchers comply with the law.
In addition to legality, pricing is another critical aspect to consider. Some sellers may offer 2C-B-FLY at exorbitant prices, taking advantage of the high demand for research chemicals. Researchers should compare prices among different vendors to ensure they get a fair deal.


2C-B-FLY is a relatively lesser-known psychedelic compound categorized within the phenethylamine and benzodihydrodifuran classes. Its administration induces a diverse spectrum of psychedelic and entactogenic effects. Some liken its effects to a fusion of traits reminiscent of 2C-B, mescaline, and MDA. Its effects typically span 6 to 8 hours, with the potential for extended experiences of up to 12 hours at higher dosages.
Within the 2C-x family of psychedelic phenethylamines, where 2C-B is its closest relative, 2C-B-FLY stands apart due to significant differences in potency, metabolic pathways, and potential toxicity. This unique compound was initially synthesized by Aaron P. Monte in 1996.
In the mid-2000s, 2C-B-FLY debuted and generated some interest within the online market for research chemicals. However, its presence significantly diminished in October 2009 following a tragic incident. During this period, a mislabeled batch of Bromo-DragonFLY (measured in micrograms, unlike 2C-B-FLY, which is dosed in milligrams) led to two fatalities as individuals inadvertently consumed lethal overdoses of Bromo-DragonFLY, mistaking it for a standard dose of 2C-B-FLY. This unfortunate event resulted in the immediate withdrawal of 2C-B-FLY from the market. It later reemerged around 2016.
Remarkably, data concerning the pharmacological properties, metabolism, and toxicity of 2C-B-FLY are scarce. Additionally, its history of human usage remains notably limited. Street-level sales of this substance are undocumented, with online research chemical vendors being its primary distribution source.
Given its marked potency and the sensitivity of its dose response, numerous reports emphasize the importance of distinguishing the effects of 2C-B-FLY from a mere substitute for 2C-B. Individuals contemplating its use are strongly urged to cautiously approach this formidable, long-lasting, and unpredictable hallucinogenic substance. Employing appropriate harm reduction strategies and taking necessary precautions becomes imperative when engaging with 2C-B-FLY.

History and culture

In a 2007 interview featured in a MAPS newsletter, Ann Shulgin disclosed her fondness for 2C-B-FLY, considering it one of her preferred psychedelic substances. She also acknowledged that this compound exhibited a notably wide range of user responses.
Ann Shulgin said, “I frequently mentioned that something called 2CB Fly (sic) was delightful for me. I found it to be an exquisite experience, particularly in eroticism. However, I realized that my enthusiasm didn’t resonate with others. I noticed that by sharing my positive experiences, I inadvertently sparked curiosity. The internet became inundated with discussions about 2CB Fly (sic), and people began to inquire about it. To my chagrin, it was a letdown for most individuals.”


2C-B-FLY represents a substituted compound situated within the phenethylamine and dihydrobenzofuran chemical categories. This intriguing molecule consists of a phenyl ring linked to an amino (NH2) group through an ethyl chain and encompasses a bromine atom attached to carbon R4 of the phenyl ring.
This substance is an unconventional psychedelic phenethylamine, closely akin to 2C-B. It functions as the dihydrofuran counterpart of 2C-B, integrating the methoxy groups connected to R2 and R5 of 2C-B into five-member dihydrofuran rings fused to the central benzene ring.
Within the realm of phenethylamine derivatives, 2C-B-FLY finds its place in the category known as the FLY compounds, named for their distinctive resemblance to insect wings. These compounds feature two tetrahydrofuran rings that assume a wing-like formation adjoined on opposite sides of the central benzene ring. The strategic placement of the two methoxy groups within the five-member rings ensures optimal receptor binding, resulting in heightened potency compared to the less rigid structure of its counterpart, 2C-B.


2C-B-FLY represents a psychedelic phenethylamine, and it serves as the dihydrodifuran counterpart of 2C-B.

While our understanding of the comprehensive mechanism behind its effects remains limited, it is hypothesized that 2C-B-FLY’s psychedelic impact stems from its activity at the 5-HT2A receptor, acting as a partial agonist. Nevertheless, the precise nature of these interactions and their contribution to the psychedelic experience continue to be the focus of ongoing scientific inquiry.

Subjective effects

Compared to 2C-B, this compound exhibits significantly heightened physical sensations, intensified visual effects, more intricate geometric patterns, and profound internal hallucinations akin to substances like mescaline, 2C-E, or MDA at higher doses. Lower doses tend to lean towards entactogenic effects rather than the classic psychedelic experience.

Please note that the effects listed below are based on the Subjective Effect Index (SEI), a collection of anecdotal user reports and personal observations from contributors to PsychonautWiki. As such, they should be approached with a degree of skepticism.

It’s also important to recognize that these effects may not manifest consistently or predictably, with higher doses more likely to encompass the full spectrum of effects. Higher doses also increase the risk of adverse effects, including addiction, severe harm, or even death ☠.

The toxicity and long-term health consequences of recreational 2C-B-FLY use have not been scientifically investigated due to its status as a research chemical with limited human usage history. As a result, the exact toxic dosage remains unknown.

Anecdotal reports from individuals in the community who have experimented with 2C-B-FLY suggest that trying the substance at low to moderate doses on its own is not associated with apparent adverse health effects. However, absolute certainty cannot be guaranteed. It is essential, however, to conduct independent research to ensure the safety of combining two or more substances before consumption.

It is highly recommended to practice harm reduction when using this substance.

Tolerance and Addiction Potential:

2C-B-FLY is not considered habit-forming, and repeated use may decrease the desire to use it. It typically self-regulates.

Tolerance to the effects of 2C-B-FLY builds almost immediately after ingestion. Subsequently, it takes approximately three days for the tolerance to reduce by half and about seven days to return to baseline (assuming no further consumption). Notably, 2C-B-FLY produces cross-tolerance with all psychedelics, meaning that after using 2C-B-FLY, the effects of other psychedelics will be diminished.

Dangerous Interactions:

Warning: Many psychoactive substances, which are reasonably safe when used individually, can become hazardous and even life-threatening when combined with specific other substances. The following list highlights some known dangerous interactions (though it may not cover all possibilities).

Always conduct independent research (e.g., through Google, DuckDuckGo, PubMed) to ensure the safety of combining two or more substances. Some of the interactions listed below have been sourced from TripSit.

  1. Lithium: Lithium, typically prescribed for bipolar disorder treatment, is known to significantly increase the risk of psychosis and seizures when used with psychedelics. This combination is strongly discouraged.
  2. Cannabis: Cannabis can unexpectedly amplify and unpredictably interact with the effects of 2C-B-FLY. Caution is advised due to the potential for increased risk of adverse psychological reactions such as anxiety, paranoia, panic attacks, and psychosis. Users should start with a fraction of their usual cannabis dose and take extended breaks between hits to minimize the risk of unintentional overdose.
  3. Stimulants: Stimulants like amphetamine, cocaine, or methylphenidate have wide-ranging effects on the brain and alter dopaminergic function. Combining these with 2C-B-FLY can elevate the risk of anxiety, paranoia, panic attacks, and thought loops. This interaction may also increase the risk of mania and psychosis.
  4. Tramadol: Tramadol is known to lower the seizure threshold, and psychedelics can potentially trigger seizures in susceptible individuals.
  5. Potential MAO-Altering Effects: If 2C-B-FLY has suspected monoamine oxidase (MAO)-altering effects, it might raise the risk of serotonin syndrome or general monoamine overload, particularly at high doses, when combined with MAOIs, stimulants, or substances that modulate neurotransmitter levels like serotonin, dopamine, and norepinephrine through unknown mechanisms.
