This sounds like an interesting material, which has supposedly become available. I can't find much information about it yet.
There is a trip report out there. It makes it seem like bk-2-cb is a proper psychedelic rather than a stimulant. Does any one know any more?
I've been able to try this at 111mg.
Very pleasant, and the experience itself is hard to tell apart from 2C-B. I actually liked the experience more than 2C-B as I was in even more control than with 2C-B itself, and incredibly blissful.
The trip lasted longer than 2C-B for me, about 11-12 hours total from taking my dose to being baseline again, whereas 2C-B is more like 5-7.
As far as time frames go, for me I had first alerts some time around 10-15 minutes after dosing, was fully tripping within about 60-90 minutes, and I reached complete peak around 4-5 hours in, then stayed there for the next 3-4 hours, then began a gradual descent.
For me there was a DOx like "comedown" with this, in the sense that the last few hours I was left with a lot of muscle tension and too stimulated to sleep, while still being mentally tired and wanting to be able to sleep already. I'd say it was worse for me in this respect than DOB or DOC were, but this was only present during the last 2-3 hours of the trip, and I didn't notice any muscle tension or bodyload of any sort during the rest of the trip.
If I'm very well rested or have a couple of beers or a benzo for the tail end of the trip then I'd pick bk-2C-B over 2C-B in most cases, if not or if I was pressed for time it'd be a harder choice and I may lean towards 2C-B.
I have to say I very much disagree with it being 10x less potent than 2C-B though based on my experience. I found 111mg of bk-2C-B to be similar potency to 40mg of 2C-B. I think maybe at smaller doses like 80-90mg yeah it might be equipotent to 8-9mg of 2C-B, but as the dose rises it looks like there's a steep dose response curve and the difference in potency quickly becomes a lot less. I certainly don't think for example that doses of 300mg+ would be even remotely close to reasonable with this one, whereas I'd be more than happy to take 50 or even 60mg+ 2C-B.
That said it may be as Solipsis suggested, that potency will vary quite a bit. Even if this is the case I would advise being careful with the dose. I think post allergy test, 70-80mg would be a good range for people just wishing to dip their toes in, then more like 90-100mg for a standard experience, and 110-130mg for a notably stronger one. If you find it's not enough then increase as necessary.
I also wrote a report but it's very messy and I stopped writing it at 8 hours in so I'll have to give it a read through and clean up but I should get it up some point soon.
βk-2C-B (2-amino-1-(4-bromo-2,5-dimethoxyphenyl)ethan-1-one, Bk-2C-B) is a psychedelic drug which is structurally related to 2C-B and methylone. It has similar effects to these drugs in humans and has been used as a recreational drug.
Conventional theory suggested primary βk-primary amines would be too prone to dimerisation to ever exist but βk-2C-B.HCl is stable when kept dry. Exposure to neutral or basic aqueous solutions causes reaction to a purple solid.
The dosage is 80-120mg and the duration is approximately ten hours, notably much longer than 2C-B. This is unexpected as the β-ketone moiety typically reduces duration of a drug.
βk-2C-B turns bright orange when exposed to the marquis reagent.

I was just about to inquire about this one.. saw a person who blamed his purple snot on this.. tbh I wasn't sure if I should look in the Phenethylamines or beta-ketones. He claims that the subjective effects are "somewhat more interesting than 2c-b" (his words).. which isn't saying a whole lot.
Have any other bk-2c-x chemicals emerged. Bk-2c-e, bk-2c-i, bk-2c-c would be interesting to explore.. not sure I'd jump on bk-2c-p though ;-)
I am also not sure about taking a drug that turns my bodily fluids purple.. I have no plans to clog my sinus cavities with a purple solid.. and not sure how that would go with the rest of my internal organs honestly.. I think the reaction that causes this needs to be investigated a bit
Considering that humans are full of aqueous solutions
MORE INFO- I questioned that dude, and researched a bit to confirm as much as I could
omg a bad idea
no proof, but its probably too volatile
in a cap or wrapped up.. stomach acid is key
slow onset of weak effects and purple snot
* basically any ROA that allows the chemical to come into contact with a water based liquid will result in a fairly inert purle dimmer..
From around the web
Plugged 50mg almost instant enema. Same 2 hrs later. Small amount nasal (20mg) stung like hell, think I blew it all out. Minor entactogenic effects but not surprising given total body rejection.
Quick question...Did it turn purple in solution, lol.
Yes it did indeed, seemed to dissolve ok.
Possible that this purple/pink stuff is due to dimerisation. That's my thinking here - just a hunch. AFAIK, this is less likely to occur in acidic environments? Which the gut provides readily.
So prepping this in tap water may well reduce the potency of the compound (even some M ions to potentially help the reaction along) -depends whether reversible. So those attempting plugging might want to try acidifying the solution to see if it helps (bit of citric, perhaps?) :/
I do recall someone else having a big fail from plugging this.
do not mix with water! you will ruin your product in 5-10 minutes..
Do an allergy test for the love of god.. and start slow.. after 100mg the effects per mg gets much steeper than <100mg
ORAL - Gel cap, wrapped in a paper towel or any other method that ensures the product goes to your stomach acid first
honestly I would avoid this until we have more information about the purple dimmer.. which I believe is two of the bk-2c-b molecules attached together.. I mean you don't want to end up looking like:
Both of the individuals who tested this have clarified their subjective effects. Both agreed that it was closer to street ecstasy pellets than any 2c-x. At 150mg no visuals were noticed, maybe color appreciation. The body load shifts from pleasurable to harsh at that dose.. 100mg was underwhelming, the body buzz was the highlight.
Headspace was fairly clear, with pleasurable moments.. those moments were at times competing with nausea with both individuals .. 10 hours is about right.. sketchy comedown
I watched the dimmerisation in water.. its quick and the final product kind of looked like jelly..it reminded me of adding cornstarch to make a sauce.. sweet and sour. Yum.
They agreed that snorting is just as awesome as any other 2-c.. lotts of pain.. but with the added bonus of an extremely uncomfortable drip
I wonder if the other members of the 2c(BK) family Will have the same shade of dimmer
Its like a drug with a built in test kit.. almost idiot proof ..
Anyway, everyone I know who has tried it hasn't thought too much of it.. a lot of it was sacrificed to show others that it turns color in water..and in noses, which doesn't look like it feels very good.. it reminded me of "dumb. Ass who just railed 2ce" face.. or the "dumb ass who just railed Smarties candies" face..
Bright side is, its easy to identify.
Oh, the intensity of the bodyload seems to vary.. and the onset seems to vary greatly between people.. 45 mins to 1.5 hours or so
Oh dear guys. My friend is trashed!! My friend was a bit of an idiot. He had drunk some beard at around ten until 12, ten UK units of aclcohol. Then just today he got some BK-2-CB and some 5-MEO-DALT in the post, and also just bought some tasty green stuff My friend then smoked some and just did some BK-2-CB by snorting it. My friend is MessY!!!
Just an anlergy test though, maybe around 10-40mg. He just eyeballed the dose LOL!! What an idot, lolo he wont be doing that agains!! ahhhaha....!!!! my friend needes to chill out !!!!!! oh dea.... fjfoj
ok guys,,, My friend wil so a trip t triport tommorow when he taeks some more aferter the allerg test. TOMMOwrwew at around 5 in the morning.. ok... so tripi report tommore.
Lol i have been on the is forum sand this is m y firdt post in 4 years. Huy guys!!! I AM A Long tome lurker but tis is my first post!!
I will ger my friend to right a trip report for tommorws trip!!!
STAY SAFE !!!
Remeber, start SLOW, and, LOW... Take it safe!! Peace out !!
Glad you waited 4 years for that gem to shine through the ruff. Hope you take more care when posting sober, as you do weighing out potent mind altering substances while under the influence of a dangerous depressant; like alcohol.

As far as this purple color.. could be from the bromine. Acidic water reacts with Potassium Iodide to give off a light yellow color when the white crystals are added to acidic H2O. I2 and Br, both halogens used in the synthesis of these compounds.
