Bk-2C-B

βk-2C-B (also known as Bk-2C-B, or beta-keto 2C-B) is a novel synthetic psychedelic substance of the phenethylamine chemical class that produces psychedelic effects comparable to members of the 2C-x family when administered.

Compared to its structural analog 2C-B, its effects are often described as being considerably more stimulating and less psychedelic with a significantly longer duration. This compound is relatively uncommon and has little to no history of human use prior to its 2014 distribution by online vendors as a research chemical.]=+]=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.
