Thyroid medication

Does anyone have any knowledge on how to use Armour Thyroid medication for weight loss? Dosages,etc. Thank you for any advice.

I have taken Armour thyroid for many years after a bout with thyroid cancer left mine on the operating floor. I can tell you that I take 4 1/2 grains a day (up from 3 grains a day when I was younger)and my metabolism is great. However, I am not sure that taking this medication as a way to lose weight is the most propetious way to go about it. Items such as Mua Huang may have less of a permanent health risk.
