Oh right! I was under the impression (probably haven't been on the forums enough or read enough of the Cutler protocol info) that low dose DMSA was used much more often than DMPS.
I will check more into the full program. what I basically knew was small frequent doses of DMSA and then C, E & minerals frequently too, then later on down the track add ALA. Now I just have to find low dose DMPS! Thanks.
