My husband took Qucertin Plus (prostasol) from Mexico to lower his PSA. He had prostate removed in 1999 but recent PSA went up to 5.5 where for years it was always remaining in the 3 range. His PSA after four weeks of prostasol dropped to 0.0 and his testosterone has dropped to 6 from 200. The Dr. thinks we should do PSA test monthly and not take prostasol until it begins to climb again. We are going to MD Anderson next week so we will see what they recommend.
