Trip Reports – Bk-2C-B

The below is an account of experiences with BK-2C-B, it’s a combination of effects experienced in various doses ranging from ±30mg up to 100mg.

Route of administration: It is widely documented on various forums that BK-2C-B reacts to contact with water and turns into a purple goo as a result, making it useless (and potentially dangerous) in that state. In someone’s experience the best effects are achieved by dosing orally, on an empty stomach.

Wrap the measured dose in a rizla and wash it down with a small amount of water that has been acidified with a generous helping of lemon or lime concentrate. As stated before, water does not mix with this substance. Fill the glass with enough water for one regular sip of water (just enough to wash down the rizla) and add the concentrate to this in roughly a ratio of 1 part concentrate to 10 parts water. It’s better to be generous with the concentrate. Acidifying the water means it will not turn the substance into a useless purple goo.

Consistency of effects: This person has had a variety of experiences with BK-2C-B, but always consistent effects. Research shows a lot of people seem to have very varied experiences with the substance, it seems the ROA described above gives the most reliable effects.

Duration: regardless of dosage, this substance’s effects last a long time. The first effects are felt about 30 minutes – 1 hour after ingesting. After that the experience seems to be pretty stable throughout, reaching a peak roughly 1 hour after first effects are felt. The peak can last anywhere from 10 – 14 hours. The afterglow is very subtle, almost unnoticeable and lasts a further 1-2 hours.

Negative effects: Online there are people reporting strong headaches during the comedown. It seems that the substance increases the frequency of urination, which means it is important to stay hydrated throughout. Not doing so could possibly result in the headaches described on online forums. Nausea can be experienced during the come up, the nausea is generally mild and manageable, higher doses could induce purging (but this seems to be rare). For a full breakdown of negative physical effects please refer below.

Overall: BK-2C-B effects seem to follow the general head-space you are in and overall seems to be easy to control and steer by the tripper.
