Hi there
I went to Sharkeys for about 4 months. I found them to be very similar to a local natropath in what they recommended with diet, lifestyle etc and another natropath I had tried had also given a formula like Sharkeys. The only thing was that Sharkey's was twice the price. I wasn't convinced so I stopped going to Sharkeys and went back to my original natropath.
I have heard their many success stories too but it didn't work for me.
Good luck though.
