Now you guys tell me!!!! I couldn't find it in injectible form _anywhere_ . Nobody, at the time, even suggested that an injectible form exists. Even the drug companies who make the stuff. Maybe, since I live in a city and don't have rural connections this was clearly a handicap in this case. Nevertheless, I received a drug information sheet from one of the drug companies. That's where I obtained the info re: drug activity and pH. The water must be kept as acidic as possible. (I had mine at 6.4 -6.6) At least keep it below 7. Dr. G.
