I did have a hair test, but like you mentioned, just because it didn't show up doesn't mean it isn't there. It was very high in aluminum...but stated that I still could have mercury that wasn't showing. I have had all Amalgams removed about 7 years ago.
The glutathione was a suppository, so it bypassed the digestive route, but perhaps still didn't work. I have used chlorella, but not the cutler protocol you mentioned. I have also used cilantro, but again, not the way you mentioned.
I will go read up on it and try it and thank you very much :)
