About 8 years ago I tried
Adipex P....I'm figuring its the same stuff. However, the doc prescribed it for me and it was like $40 from the pharmacy a month. It was before I started any type of training and was just wanting to lose weight. It absolutely kills hunger. Infact I ate so little that my hair was damaged and became brittle because of the lack of nutrition(vitamins and just food).
I lost probably 40 lbs of fat and probably as much muscle. But all I cared about was getting skinny.
Make sure she drinks much water.....very easy to dehydrate on adipex....I know.... I did.
