actually I have strong reaction against DMSA also. However I tolerated DMPS just fine.
You have to understand that when people say DMPS is risky this is ONLY a cause they don't understand how to use it. If you give 500 mg of DMPS in an IV that is dangerous, bordering on criminal.
The way to use DMPS you start out with very very small doses and and then you must take it every eight hours on the dot. If you do it this way, which is the correct way, you will be just fine
if you have success with chlorella, then more power to you. However if it doesn't work out I HIGHLY recommend you look at th Cutler protocol. In fact I would recommend you try it before you try the chlorella. Join that Yahoo group I linked and ask them about your situation, they will be able to help you
