This is where I ordered the ASAP and the nasal spray. They have a 10 ppm and a 22 ppm version. http://www.hartamerica.com/ASAP%20Silver%20Solution.htm
I can't remember where I got the silver solution. I am going to run out soon though and I am going try to find the argentyn 23 that is 23 ppm. I think I read that GNC sells the silver solution under a different name.
I don't take the three teaspoons a day. I use about three squirts in each nostril and pinch my nose and hang upside down on an inversion table and let it absorb. I also squirt it a few times in my mouth and let it absorb.
I don't undertand why I got betterso fast with the ASAP brand. In about a week I was about 80% better and I didn't seem to herx at all from it. If it really killed the Lyme bacteria I should have herxed. I don't know of anyone else tried this for Lyme Disease to see if it helps other people.
