Legality and Compliance:
One of the primary concerns with online 2C-B vendors is the legal aspect. In many countries, 2C-B is considered a controlled substance or a scheduled drug, making its sale and possession illegal. Buyers should be cautious when dealing with sellers promoting 2C-B for sale, as engaging in such transactions can have severe legal consequences.
Transparency and Accountability:
Research chemical sellers often lack transparency and accountability in regulated markets. Many operate anonymously and may not provide sufficient information regarding their products’ quality, purity, or source. This lack of transparency poses severe risks to consumers, as they have no way of verifying the authenticity or safety of the substances they buy.
Safety and Health Risks:
Purchasing 2C-B from online vendors can expose buyers to significant health risks. The absence of quality control measures can lead to the distribution of impure or contaminated substances, potentially causing adverse effects, overdoses, or long-term health consequences.
Supporting online vendors selling 2C-B and other research chemicals raises ethical questions. These substances often bypass rigorous safety and efficacy testing conducted in pharmaceutical research. Buyers inadvertently contribute to a market that operates in a legal gray area and lacks ethical oversight by purchasing from such vendors.
4-Bromo-2,5-dimethoxyphenethylamine, commonly known as 2C-B or by various street names like Nexus, Bromo Mescaline, BDMPEA, and Venus, is a novel psychedelic compound belonging to the phenethylamine class. It is the most prominent member of the 2C-x family, sharing structural similarities with the classical psychedelic mescaline. While the precise mechanism of action remains incompletely understood, it is believed that 2C-B primarily exerts its effects by binding to serotonin receptors.
In 1974, American chemist Alexander Shulgin made the significant discovery of 2C-B while exploring psychedelic phenethylamines derived from mescaline. During the 1970s, a select group of American psychotherapists found therapeutic value in 2C-B due to its brief duration, limited side effects, and relatively mild nature. It gained a reputation as a valuable substance for therapeutic purposes.
However, its recreational use soon emerged, and briefly, it was commercially available under names such as “Erox” and “Nexus” in specialty shops and adult video stores. In 1995, it was classified as a controlled substance at the federal level.
Subjective effects of 2C-B encompass open and closed-eye visuals, time distortion, euphoria, and ego dissolution. Users have described it as a moderately warm, colorful, and highly sensual experience. Unlike tryptamines like LSD or psilocybin, which can induce profound introspection, 2C-B tends to emphasize the visual and tactile aspects of the psychedelic experience.
Lower doses (under 15 mg) are reported to enhance sensory perception and aesthetics, akin to MDMA, to some extent. In contrast, higher doses produce a distinct and profound psychedelic experience, affecting the user’s mental state.
While 2C-B appears well-tolerated physiologically, more research is needed to fully understand its safety profile. It is generally believed to share similarities with classical psychedelics, characterized by low abuse potential and toxicity. However, it is essential to acknowledge the potential for adverse psychological reactions, particularly in individuals predisposed to mental disorders. These reactions may include severe anxiety, paranoia, delusions, or psychosis. Therefore, responsible use and caution are paramount when engaging with 2C-B or any psychedelic substance.

History and culture
1974 American chemist and pioneering psychedelic researcher Alexander Shulgin synthesized and investigated 2C-B for its psychoactive properties. His exploration focused on novel psychedelic compounds with chemical structures reminiscent of mescaline.
Shulgin documented his discoveries in the 1991 book “PiHKAL,” where he categorized 2C-B among the “magical half-dozen” of psychedelic phenethylamines, a selection he considered particularly significant. This esteemed list included mescaline, DOM, 2C-B, 2C-E, 2C-T-2, and 2C-T-7. Shulgin frequently expressed his personal preference for 2C-B as his favored psychedelic experience.
During the 1970s, a few psychotherapists in the United States began utilizing 2C-B in their patient treatments. They reported that the compound facilitated warm, empathetic connections between therapists and patients, assisting in dismantling ego defenses and inner resistances. This, in turn, allowed patients to access suppressed emotions and repressed memories. The gentle and manageable effects of 2C-B and its short duration and limited side effects made it an appealing choice for therapeutic contexts.
Subsequently, 2C-B transcended its therapeutic origins and found popularity within the recreational drug scene. It gained favor as a substitute for MDMA in rave and club settings due to its comparatively mild comedown and ability to induce a lucid, euphoric state of mind.
In the 1980s and early 1990s, several foreign companies legally manufactured 2C-B, marketing it under brand names like “Nexus,” “Erox,” and “Performax.” These products were promoted to address issues like impotence, frigidity, and decreased libido. They were available at adult book and video stores, “head” shops, and even certain nightclubs. Notably, the DEA documented the distribution of yellow pills in Miami, Florida, marketed as an aphrodisiac.
In the United States, 2C-B gained prominence as an alternative to MDMA after MDMA was classified as a Schedule I substance in 1985. Consequently, 2C-B was also placed in Schedule I in 1995. Its resurgence in the 2000s was facilitated by the emergence of the “research chemicals” and “designer drugs” scene, along with the availability of darknet markets.
Remarkably, 2C-B was legally obtainable in Southern Africa from 1993 to early 1996, where it was marketed as “Ubulawu Nomathotholo,” loosely translating to “Medicine of the Singing Ancestors.” It was positioned as a remedy for traditional healers known as Sangomas.
2C-B, scientifically known as 2,5-dimethoxy-4-bromophenethylamine, falls into the category of substituted phenethylamines. These compounds are a class of organic substances built upon the phenethylamine structure, characterized by a phenyl ring linked to an amino (NH2) group via an ethyl chain. In the case of 2C-B, it exhibits methoxy functional groups (CH3O-) attached to carbons R2 and R5 and a bromine atom affixed to carbon R4 within the phenyl ring.
Furthermore, 2C-B is a member of the 2C family of phenethylamines, all sharing the common feature of methoxy groups located at the 2 and 5 positions of the benzene ring.
In contrast to most psychedelics, 2C-B has demonstrated a unique pharmacological profile as a serotonin 5-HT2A receptor with low efficacy, functioning as either a partial agonist or, in some cases, a full antagonist. This intriguing property implies that the effects elicited by 2C-B users are primarily mediated through the 5-HT2C receptor. Additionally, research indicates that 2C-B can elevate dopamine levels in the brains of rats, potentially contributing to its psychoactive properties.
Nevertheless, the precise role of these interactions and how they culminate in the psychedelic experience remains an enigma, presenting an ongoing challenge for scientific understanding.

The toxicity and long-term health implications of recreational 2C-B use remain unexplored in scientific research, and the precise toxic dosage remains undisclosed.
Based on anecdotal accounts, no discernible adverse health consequences appear to be associated with infrequent or low to moderate doses of 2C-B when used in isolation. However, it’s essential to acknowledge that nothing can be guaranteed absolutely.
It is strongly recommended that individuals employ harm-reduction strategies when engaging with this substance.
2C-B at typical doses is unlikely to induce neurotoxic effects. By rough estimations derived from data involving rat cortical cultures, the IC50 of neuronal activity suggests that neurotoxicity may occur at doses exceeding 330-650mg. In practical terms, users should avoid high doses to prevent potential long-term harm, but standard doses are generally considered safe.
Some users have reported hypertension, hyperthermia, and tachycardia at elevated doses. Consequently, individuals with pre-existing heart conditions should abstain from 2C-B use. Users should monitor their heart rate and body temperature and respond accordingly. Engaging in strenuous physical activities while on 2C-B is discouraged.
There is no available data on the LD50 (lethal dose) of 2C-B. However, it is believed to be considerably higher than the effective dose. For reference, Alexander Shulgin reported the consumption of a 100 mg oral dose without apparent harm.
Dependence and Abuse Potential:
2C-B, like other serotonergic psychedelics, is generally regarded as non-addictive with a low potential for abuse.
Tolerance to the effects of 2C-B does not typically develop immediately after ingestion. Many anecdotal reports indicate that individuals have consumed this substance over consecutive days, redosing numerous times, without an immediate tolerance buildup. Tolerance tends to increase slowly, even under sustained exposure. Notably, 2C-B does not exhibit cross-tolerance with other serotonergic psychedelics, although some users report that other psychedelics may affect 2C-B tolerance. For instance, using 2C-B followed by LSD does not diminish the effects, whereas the reverse sequence results in reduced 2C-B effects. However, this one-way tolerance appears to be an exception, with most individuals experiencing cross-tolerance between 2C-B and other psychedelics.
It’s crucial to note that many psychoactive substances, which are relatively safe when used alone, can become dangerous and potentially life-threatening when combined with specific other substances. Here are some known dangerous interactions to be cautious of:
- Lithium: Lithium, commonly prescribed for bipolar disorder, is strongly discouraged when used alongside psychedelics due to the heightened risk of psychosis and seizures.
- Cannabis: Combining cannabis with 2C-B can lead to a potent and unpredictable synergy, significantly increasing the risk of adverse psychological reactions such as anxiety, paranoia, panic attacks, and psychosis. Caution is advised, with users recommended to start with a reduced cannabis dose and take extended breaks between hits to prevent unintentional overdose.
- Stimulants: Stimulants like amphetamine, cocaine, or methylphenidate can interact with psychedelics, potentially elevating the risk of anxiety, paranoia, panic attacks, and thought loops. This combination may also enhance the chances of experiencing mania and psychosis.
- Tramadol: Tramadol is known to lower the seizure threshold, and when combined with psychedelics, it could potentially trigger seizures in susceptible individuals. Caution is strongly advised.
