bk-2C-B HCL

What is bk-2C-B HCL?
βk-2C-B (also known as Bk-2C-B, or beta-keto 2C-B) is a novel psychedelic substance of the phenethylamine class. It is a structural analog of 2C-B.
Subjective effects include open and closed-eye visuals, time distortion, euphoria, and ego loss. Compared to 2C-B, its effects are often described as being considerably more stimulating and less psychedelic with a significantly longer duration.
Bk-2C-B is relatively uncommon and has little to no history of human usage prior to its 2014 distribution by online vendors as a research chemical.[1][2]
Very little data exists about the pharmacological properties, metabolism, and toxicity of Bk-2C-B. As a result, users are advised to approach this novel and poorly understood hallucinogenic substance with the proper amount of precaution and harm reduction practices if choosing to use it.
Chemical Properties
βk-2C-B, or beta-keto 2C-B, is a substituted phenethylamine featuring a phenyl ring bound to an amino (NH2) group through an ethyl chain. βk-2C-B contains the structure of 2C-B substituted with a ketone group at the beta carbon of the structure (R1). βk-2C-B contains methoxy functional groups CH3O- attached to carbons R2 and R5 as well as a bromine atom attached to carbon R4 of the phenyl ring. βk-2C-B belongs to the 2C family of phenethylamines which contain methoxy groups on the 2 and 5 positions of the benzene ring.[9]
Pharmacological effects
Bk-2C-B likely acts as a 5-HT2A partial agonist. The psychedelic effects are believed to come from its efficacy at the 5-HT2A receptors. However, the role of these interactions and how they result in the psychedelic experience continues to remain elusive.
Some of the most commonly reported effects are:
Spontaneous tactile sensations
Colour enhancement
Pattern recognition enhancement
Visual acuity enhancement
Distortions
Drifting (melting, breathing, morphing and flowing)
