The methods being described in the articles are not what I have been doing. Those are for acute high dose metal poisoning and are very dangerous even when they are truly required. Even the oral versions I use warn not to use them long term for the reasons stated in the articles. If people are getting IV high dose chelation as a method of therapy then yes I would agree that is dangerous and reckless behavior of whatever doctors are doing this. That would be akin to getting TPA shots for therapeutic reduction of arterial plaque.
I used my methods on and off watching my BP over a period of time and watched for the valley floor.
