After taking TKI for over two years, last two tests were below 0.01% but still not undetected yet. Have read the article about PGE1 and Misoprostol for eradicating CML stem cell. I couldn't get myself Misoprostol, however I read that Evening Primrose oil is one of the best resource of PGE1, and Selenium might play a good role in CML as well. I decided yesterday to start taking these two supplements. Let's see how it goes, will keep updating in this thread in case any news.
