yes but what do you test the urine with?, Everything I have read about dmsa and all those is that there not very good for you. and that you should be seeing a doctor while using them.
I bought two urine test's from http://www.heavymetalstest.com/_general.php I'll see if it actually shows anything. I have the zeolites (or whatever there called don't have them in fron tof me) and ordered 4 bottles of the modifilan I was hoping for a more natural aproach than dmsa and the others.
