Endocrinologists are probably no more likely to prescribe thyroid with those numbers than a GP. Maybe even less so.

If you want to experiment with thyroid hormone go see a NP or ND -- nurse prac, or naturopathic doctor. You can probably google one up. Taking synthroid probably won't help the low T3 since it is T4 only.

I never really had good results from armour or natural thyroid medications. I'd start off feeling fantastic then a few weeks in I'd feel just horrible.
