She needs to be off everything when she gets her bloodwork. No steroids or t3. Make sure that she's able to get help for her condition so that she'll actually know what needs to be done without guessing. As far as anavar to prevent catabolism, 2.5mgs would be more than enough. 1mg would be plenty if you can dose it that low. Just make sure she's off everything for a few weeks before her check up.
