That appears to be the one; they seem to be offering more to the public than they used to. But they are legitimate, mainly used by physicians.
I had aluminum poisoning which was discovered a couple of years ago and it took a few treatments to eliminate it - don't remember exactly how many. I believe it depends on the extent of the toxicity and the type of heavy metal.
Unfortunately, my dr says the oral chelation is pretty much a waste of time and money. That would be so much easier than having it done intra-venously. However, if heavy metal poisoning is really the problem, it's definitely worth it. No one knows how I got the poisoning, but the difference in how I felt was like night and day.
