I have. the last one was 'ormus'( pure gold extract). I also found good result with radionics software (EASYrad = $50 US). There is also a free version to try. It basically uses the required frequencies and it is one of the most of effective software for manifestation. There are many expensive software but this one could beat any available ones. I used melatonin and iron tablets as well, but there is no significant change. The principle is = we need more energy to manifest things. So just working on chakras are not enough. Therefore, a higher energy source like radionics is necessary. Radionic software can replace the devices. I get quick result with radionic software (Easyrad).
