10 - 50 mg sublingual 2C-B (liquid)


My prior experience with drugs was fairly limited. Mostly marijuana and one amazing encounter with LSD. One other trip to mention is the one time I did spice. My friends and I are almost certain it gave me a seizure.

I have always been attracted to hallucinogens rather than stimulants, but I didn't have any real hookups. I figured it was time to give The Silk Road a try (this while it was still operational, obviously). After investigating 2C-B, I decided it was my best bet. It was cheap, relatively risk free, and the seller was quite reliable. I purchased 500mg, which turned out to be far more than I could easily use. I had a somewhat unreliable milligram scale, which was only good for weighing 50mg or more. I weighed the powder, and it was spot on 500mg. I used liquid dilution in a syringe, making 1/5ml equal to 10mg 2C-B. I am going to quickly summarize most of my trips, and focus on a few that stood out. All doses were sublingual, held in the mouth for 3-5 minutes before swallowed.

I began with an experimental dose of 10mg. The setting was pretty crappy, my parents were around, and I didn't have a sitter. It turned out to be a weak dose for me. Only mild distortions, without a mind-fuck. I enjoyed the mini trip, but I needed something more intense.

Over the next few days, I tried some larger doses. In the beginning, I did not enjoy the trips. The negative aspects of the drug were too apparent. I always got a fever, which made me achy and nauseous. Sometimes I would have a temperature up to 101-102F. The hallucinogenic aspects were pretty amazing, though. Generally, they were characterized by wonderful warping and blooming effects, along with an intense feeling of floating. It was almost like dreaming, and strangely dissociative. The comedown on 2C-B was easy for me. It let me down slowly, eventually taking me back to reality after 4-5 hours, and a had short-lived afterglow only lasting a few hours.

After my fourth trip, I began taking 400-600mg of ibuprofen to reduce the body load

, and water to make myself fully hydrated. It did wonders for me. Since then, I haven’t felt sick while tripping.

I quickly realized that I did not particularly enjoy the come-up, regardless of how wonderful the visuals were. I found it uncomfortable, and abrupt. However, once the first peak hit (+1-2 hours), I loved it. Immediately after the peak, the trip was joined by an opiate-like buzz. Even though I still tripped extremely hard after the first peak, the opiate feeling made me comfortable with it.

I decided to take the plunge, and dose up 50mg. I decided to trip in my room, because I suspected I wouldn't be able to socialize well.

T+ 0:00 Took 50mg sublingually at around 3:30 PM. Tasted terrible, but I kept it in my mouth for 5 minutes or so before swallowing. Picked up a book and started reading.
T+ 0:35 Began feeling like I had taken a shit-ton of speed. It was difficult to sit still, but not proportional to the speedyness. The body load I experienced with the previous two trips was significantly different. It felt more like a pressure in the upper neck and back and sides of the head. Later in the trip it felt like being encased in a pillow. A lot of this was due to raised body temperature, though.
T+ 0:45-1:00 Letters in the book had started jiggling around. I tried to continue reading, but every time I stopped focusing on a particular line, the letters seemed to melt and jump from line to line. I stop reading and go to use the bathroom. Holy crap! The bathroom was well lit, and the white tiles were almost burning my eyes out. They were too bright. I noticed distinct red blue and yellow in the edges of my vision. It was uncomfortable, so I got out as quickly as I could.

T+ 1:30 This was where things began to hit the roof. The clock on my wall was pulling a Salvador Dali, and colors were beginning to separate into blue green and yellow. If you are wondering exactly what shade these were, they were the same as the colors in the 'tea, coffee, 2C-B' picture with that 40's looking woman. My plaid blanket was going crazy. The colors were bleeding into each other, making it look like someone was constantly changing the hue of the fabric in photoshop. I was feeling very disassociated, I felt like I was living a dream.

T+ 2:00-2:30 The world was a dizzying, warping colorful place. My mind space had gradually been shifting, and I started to feel like the drug was screwing with my head. All of a sudden, I felt as If I was living in a fake world. I saw the past as my brain had stored it. It was fragmented and mostly empty of details. The memory of the past began to seem incomplete, a fabrication. At this point I would not have been surprised to discover that the past had not actually existed.

T+ 3:00-4:00 I had started to come down. The world wasn't as crazy anymore. The period of un-reality only lasted ~10minutes. I was feeling empty and alone from my previous revelations, so I decided to read something uplifting. It was an article about human kindness and the state of the world. I was filled with a crazy, awesome-feeling afterglow. A supreme level of contentment with reality. The closest description is that of being engulfed in a warm fuzzy blanket.
T+ 4:20 I left my bedroom, still tripping pretty hard. I felt extremely drifty and dream-like, and somewhat intoxicated.
T+ 6:00 I Had a nice meal with my family, nobody noticed anything. Pretty much back to normal state, feeling very visually and mentally exhausted.

T+ 8:00 I fell to sleep, and had a series of strange dreams, one involving an ocean made of mercury. Hmm…weird.
Woke up the next day feeling completely normal.

I still had about 300mg left, so I decided I would explore the 2C-B world further. Since then, I am down to 200mg, and I have been noticing something quite unusual. I trip on 2C-B approximately bi-weekly, and instead of developing a tolerance, I have steadily become far more sensitive to the drug.
I have steadily become far more sensitive to the drug.
A 10mg dose now makes me trip like a 25mg dose used to. 9, 8, 7 and 5mg doses hit me like 20, 15, 10, and 5mg doses respectively. A 5mg dose still doesn't do significantly more than it originally did.

During my most recent trip, I took 10mg. The height of the peak lasted a short time, but was unbelievably intense. I was watching the anime movie “My Neighbor Totoro”, and I noticed I was tripping extremely hard, even though I wasn't focusing on the hallucinations. I looked up at a picture on my wall, and the entire world began to get sucked into its edge. It looked as if there was an inward-facing waterfall surrounding the picture, and the world was falling into it. The picture began to shrink rapidly - the world falling around the picture, and the picture collapsing in on itself. I felt like I was falling off of the universe. My sense of time was barely hanging on. I’m not sure how long this lasted, but the second I came off the peak, I was encapsulated in an amazing body high. I didn't have a single worry. I felt encapsulated in a warm fuzzy blanket, completely comfortable with any hallucinations that came at me. The strength of the comedown was on par with my 50mg trip. I don’t usually smoke, but I wished I had some cigarettes. The nicotine would have enhanced the feelings immensely.

I have no idea why I might be having stronger reactions to the drug, but I am enjoying it. At this rate, I may never finish off my stash.
