Jack her in the jaw for buying you such a worthless junk 'supplement'. Lay the pimp-hand down HARD for that one.
I think you'd get better results using the Vince Goodrum 'Bee Pollen/Brewers Yeast' stack.
Tell her to go out and get you a quality protein formula, creatine, glutamine a multi-vitamin complex...then on the way home have her stop at the grocery store and stock up Y2K style on red meat, chicken, oatmeal, eggs, milk, and red-potatoes and brown rice.
Hope this helps...
