I didn't get a chance to read that entire page in depth, but what I got from it is basically to avoid IV chelation, or high dose infrequent chelation. Which are valid points by all means. These actually seem to be pretty easy conclusions to come to, as all you have to do is look at the adverse reactions and how often they happen from using DMPS in this way.

It doesn't have any mention of ALA which is crucial for getting deeply stored mercury out of the organs and brain. I also couldn't find any mention of frequent dose chelation, which is aimed at keeping a relatively steady blood level of chelating agents for days at a time. Using ALA in any other way can actually increase the amount of mercury in your brain.
