Nobody I have ever spoken to, inlcuding Cutler has ever said that ALA comes out more in Feces than Urine. The only thing that ALA and DMPS do is pull the Hg out into the blood system so that your kidneys and liver can get rid of it. I've also never read anything that said anything about a difference in the route out of the body. If you have anything that says that I'd be very interested in reading it. Until then, I did a 2 day ALA course then took a 24 hour urine test. As far as I can see it comes out at about 1/10th the rate of DMPS, maybe slower. If it took 2.5 years for me using the most effective chelator there is, then it's going to take a hell of allot longer using ALA. I really don't see the point in doing a feces test because you would still end up with the same result, except for the ALA you'd end up with allot of Hg in your brain, but I don't know how you would measure that.
