thanks for reminding me. I bought some heavy metal urine tests to take. I will take them later tonight. But I also have tons of bottles of modifilin (sp??) and drops for your water to remove metals. But was then side tracked when I was put on the itra and told that I could not remove metals while take prescriptions forget the reason. I don't want to make the itra less effective by doing this. I have no idea whats in crap pharms you think if I took the urine test the itra might have metals in it and it give me a false reading? I know a lot of pharms do.
