She should start the T3 at maybe 20 and see where that takes her then go up. It may feel good for the first few days because natty production hasn't slowed much yet but when that slows I'd up it if 20 is no longer quite the same. Go up 10 mcg every few days until sweet spot. I'm only running 50 right now and I'm a dude at a little over 200 lb so...
