Not deadly. Ive made some about a year ago. Depending on what the ppm is depends on how much you will have to mix with water and drink. Real bitter. Higher the ppm the less you have to drink. You got to consume the right amount to get it in your blood stream where it is most effective. Took me about an hour i believe. After dosage felt a bit different from normal but not like an alcohol buzz. No vomit, nausea, headache. There are sites that show how to make, test, store, and how much to consume. I’d do it again. Not something i want to do everyday. Not sure if youd need to. Once a week possibly with other proactive measures to do parasite cleanses. Im sure these can ne found online as well. Even active parasite cleanses want you to wash everything everyday. Eggs can be everywhere. Its a none stop thing.
