Cutler except if you have high lead and you are ready to wait long before results. Safety is the main feature of Cutler protocol. I don't know if Cutler protocol is appropriate for someone caught with yeast issues. It may make us agonize with several flare-ups during many months. Lots of people from yahoo group told me yeast issues disappear between 60 and 90 rounds. This is almost 2 years of chelation. You have to think about it seriously because yeast goes mad on chelation.
For high lead, you have to take EDTA. But again Cutler advocates EDTA is dangerous if you still have mercury issues.
If you want quicker results, you have to go IV and follow non-moi strategy. Cutler would not advice it. I'll ask Trowbridge what he thinks about it. Non-moi results are very encouraging though.
