Personally, I no longer use a pipette. I simply pour it out of the bottle. I'm guessing about 30-60 ml. In the past I filled a big cup with about a third of CDS (maybe 100-120 ml of a ~300 ml cup) and the rest with water. Meanwhile, I limit myself to less (so about 30-60 ml) because it somehow causes for me a kind of disgust at high doses over time. But that is just my personal experience.
I also once saw a YT video of a Russian who mixed CDS half and half (so half CDS, half water) and drank it in front of the camera. Of course the video is deleted/censored today, so unfortunately I can no longer find it...
I think to remember that I once read that (in any study) mice were given pure chlorine dioxide and only from doses that were absolutely irresponsibly high, edema had formed over time. But no fatalities.
But maybe others can say more about this and/or their own "dosing experience".
