They had an office together before their falling out. Hal joked that it "only took him 4 years" and took me 5.
The Huggins' Protocol and supplement program is less expensive here in Tijuana. It is not required for mercury removal, but is available to those who want it. It is $5200 for the 8-Day Biochemistry and Dental Revision Clinic and $560 for the Huggins Bio-Nutritional Guide.
For chelation I used what Huggins made available years ago. It was the basic chelators of mercury. I added a few more recent chelators to it. Hal Huggins told me the best way to get mercury out is hot baths. You can go to mineral springs or use Epsom Salts . Some use clay, but I have heard some bad results, so just be careful, don't use too much of it.
