I use dessicated thyroid (armour) and have found it to be quite successful as have millions of others. Here is a link to locate a prescribing dr in your area http://www.armourthyroid.com/con_phLocator.aspx
Another dessicated thyroid source is westhroid, you can google their site. (not to be mistaken for synthroid which is a synthetic t4 only presription medication)
There is a great (very well reputed) site for information at www.stopthethyroidmadness.com that has thousands of members/followers (facebook, links etc), even links for nth (naturally desicated thryoid) prescribing physicians, although there are a few who report back the doctors were not what they posted to be.
