My first dose of 2c-b was 16 mg, which was pretty much perfect for a first time, high enough for decent visual effects and the rather unique mental effects (no mindfuck at all, rarely any psychedelics thoughts but a wonderful feeling of happiness and a talkative stimulation). The second time I had a friend weigh off 20 mg for me which was also a fine dose for the setting I took it in, it was then that I noticed that increasing the dosage slightly increases the visuals but leaves everything else pretty much the same.
The most recent time I took 2c-b I was at my own house and had my own 2c-b but I have no scales whatsoever. However I did have a pre weighted amount of 300 mg, so I figured if I took off 1/10th of that and split that between me and my boyfriend (who was doing it for the first time), it'd atleast be safe and in the worst caze a slightly too low dose. That was actually true, I was being overly careful as I had heared you shouldn't be eyeballing 2c-b (especially while already on ketamine as well, which by the way is a fine, fine combination with 2c-b).
Since after more then one hour it was still low I repeated this way of dosing but taking just a líttle bit more, again splitted between the two of us and about an hour later the trip was just right. I estimate the complete dose was around 30 mg, maybe 35, but we had taken it over the course of more then an hour so the peak wasn't as strong but the overal duration was a little longer. It was a nice dosage, definatly a little stronger then the 16 and 20 mg trips.
Could also have been stronger because we decided to try sublingual, which failed because its too soluble in saliva, it easily spreads thoughout your intire mouth and at some point you'll have to swallow, we failed holding it under our toungs after about 3 minutes but figured atleast a tiny bit should've been absorbed that way.
The taste was good by the way, I should maybe mention it is 2c-b HBR, but I found the taste to be like a very odd chemical fruit. Not bitter or sour at all, not salty and not meaty; not really sweet either. If anything sour-sweet, but it is really an odd taste to describe. I found it one of the most pleasant tasting drugs I've tried though, I bet if you mixed sugar with 2c-b you could make interesting candy (if it weren't for 2c-b being a psychedelic ofcourse, haha).
I later heared from someone it's appearantly corrosive and that you shouldn't use 2c-b sublingually but it was just once and my mouth seemed fine. Come up is a bit faster then with swallowing the 2c-b in a pill or capsule, but I'd assume slower then when insulfated. We didn't dare to sniff it up though as everyone mentions how painful that is to your nose, someone even mentioning blisters in his nose. It wasn't painful at all in the mouth though, so I'm still wondering why it hurts so much up the nose then.
Either way the eyeballed sublingual 2c-b trip was good, rather visual, interesting, comfortable. It was a higher dose because I had more of each, more visuals, more happiness, more stimulation, was even more talkative, still no noticable bodyload. I now know what 15 and 30 mg roughly look like and I still know the total pile can't be more then 240 mg, so with this batch I'll dare to eyeball again, still not advising it to anyone else but 2c-b isn't the most dangerous 2c, and atleast here in my country its the most common, best known and most used 2c.
As for the person wondering about the 15 mg dose in a club; I'd say that is about right. 2c-b makes me nót awkward around large groups of people, even the wrong kind of people, it doesn't matter any more then it would sober, especially on that dose.
