Hi, I suspect that I have a low thyroid. My last TSH number was 4.9. I seem to get cold much easier than my wife who has Graves disease. I don't have any weight problem however. I am 6 feet tall and weigh 155. But I do have a real problem in the Libedo and getting an erection problem. Could those be related and how would I go about getting a subscription to Armor Thyroid?
