I woke up to a fine morning, the sun was shining and almost no clouds in the sky around 4-5 degrees (Celsius) outside (it's winter). Has hardly seen the sun in recent months has only rained or been cloudy. Went out on the balcony to feel the sun on my skin and cat that I am currently taking care of followed me out.

Summary
BOH-2C-B (beta-hydroxy 2C-B) is a phenethylamine psychedelic, a ฮฒ-hydroxy-substituted analog of 2C-B. The ฮฒ-hydroxy substitution increases polarity, reducing blood-brain barrier penetration and yielding a gentler but longer-lasting entactogenic headspace with milder visual geometry compared to 2C-B. It is approximately 3 times less potent than 2C-B by weight, requiring higher doses for equivalent effects, and users report clear-headed euphoria, moderate body load, and reduced vasoconstriction compared to ฮฒk-2C-B. Headaches and jaw tension are common toward the end of the experience.

First of all sorry for my English.. Because there aren't many trip report about this substance I decided that I wrote one. Yesterday I ingested 67-70mg of bh-2c-b (scale was little jumpy because 4-ho-det damaged it but that's another story).
