I use DNA repair 528, 731, and 732, I run the chain 10 times for a total of 30 min per frequency per day. I have six different fingernail clippings in remote. I've been using it daily for 7 weeks, some only 4 weeks. My experiment was to watch gray hair diminish. So far, all of us have seen improvements in hair color and skin complexion. Even my 75-year dad. It takes about 3 weeks to see improvement, and about 4 -5 months to complete.
