Take the stat flush back its just a waste of money. Dilution will be your best bet since you cant get the synthetic urine. Be sure that she reads the creatine loading link in the dilution sticky, its very important for the test. I would buy yourself a couple of home test kits to see where she stands. The exercising and high fiber diets will help. Don't overload on water, just tell her to keep her body hydrated. Metamucil is a great source of fiber if you cant get enough through your daily diet. Hope this helps and good luck.
