5mg per day for the first cycle should be the starting point...remember this are steroids with androgenic sides (the ones woman do not ever want). Start off at the smallest dose and see how her first cycle goes. If she is good then her next cycle she can start at 5mg for a couple weeks then up to 10mg, and so forth. Starting at 25mg per day is very high for a woman and if she wanted to progress further think of the dosages she would have to do.
