If you don't want the alcohol then I think making small amounts and refrigerating might work for most stuff. I am not sure about the urine one though. Also not sure about freezing. Just don't know enough about it. For my urine one I put about 100 drops of tap water in a homeopathic bottle along with one drop of urine. Shook a bunch and repeated with a drop of this mixture added to the water. Kept diluting it down but I eyeballed what I thought was 100 drops for the rest. I might have done this 3-4 times. I know people say to use distilled water, but I am on well water and drink it all the time. I had my AK test it's effect on me and it cleared up my problems by about 25%. He was shocked as he was testing it, wondering what it was, but when I told him what it was he wasn't suprised. Said it was the trace immune responses in it that was having the positive effect on me. A vial of straight urine tested to having no effect on me.
