First of all I would not be doing DMSO and Miracle-Mineral-Supplement together. Research the Ramirez case by typing in DMSO and Ramirez in a search engine. It was oxidation of the DMSO that led to the problem.
As for PSA the PSA count is really a joke. A number of things raise PSA including caffeine, benign prostate hyperplasia and infection. It is not really a good indicator of cancer activity.
