I really preferred the first two books. This one just didn't have anything particularly special about it.

The previous reviews sounded good so I decided to try it. Well, it has seemed to help my nails, my hair is still thin, and as far as helping with muscle pain, no. Maybe I need a little more time. I also miss taking it twice a day so that could be why I am not noticing as much improvement as others.

Totally useless and a waste of money. It does not work like in the videos. Nothing at all grew following the instructions.
