1 grain (60 mg) of Armour thyroid contains 9 mcg of T3and 38 mcg of T4.
PTU reduces the amount of T3 thyroid hormone in the blood by reducing its secretion from the thyroid and by decreasing the peripheral conversion of T4 to T3.
T4 and T3 are both thyroid hormones.

Hypothyroidism where the thyroid is producing low levels of T3 and T4 in the body.
T3 is a thyroid hormone. Hormones occur in two different states in the body-bound (to a protein) and free (not bound to protein). A free T3 test is one that measures the concentration of unbound T3 in the blood.
T3 is triiodothyronine, and is the active form of the hormone secreted by the thyroid. T4 (thyroxine) is another form of thyroid hormone which must be converted to T3 by your body via the deiodinase enzyme. Although T3 is active, your body produces much more T4. The best way to monitor low thyroid function is by looking at TSH (thyroid stimulating hormone). TSH will be high if the thyroid is not producing enough T3/T4. For the majority of hypothyroid cases, only TSH needs to be monitored. For hyperthyroidism and some hard to treat hypothyroid cases, the doctor will test T3 and T4.
TSH is the hormone produced by the pituitary gland that tells the thyroid to produce the thyroid hormones T4 and T3.
PTU reduces the amount of T3 thyroid hormone in the blood by reducing its secretion from the thyroid and by decreasing the peripheral conversion of T4 to T3.
The hormone that regulates the synthesis and secretion of T3 (Triiodothyronine) and T4 (Thyroxine) by the thyroid gland is thyroid stimulating hormone (TSH) that is produced and secreted by the anterior pituitary gland, also known as the adenohypophysis.
According to the American Thyroid Association, T3 (Triiodothyronine) tests are useful in diagnosing hyperthyroidism and the severity of it. This is because patients who are hyperthyroid have an elevated T3 level.
T4 and T3 are both thyroid hormones.

Your thyroid responds to TSH produced by your pituitary gland by producing T4 (an inactive form of thyroid hormone). It then converts T4 into a mixture of T3 (the active form) and reverse T3 (another inactive form). Not enough T3 is likely to make you feel too cold at normal room temperatures. Too much T3 is likely to make you feel too hot at normal room temperatures.
The thyroid secretes two main thyroid hormones. One of these hormones is called 'T4' or 'thyroxine' and the other is called 'T3' or triiodothyronine. The gland secretes roughly 80% T4 and 20% T3. There are very tiny amounts of other thyroid hormones known as T2 and T1 but they don't appear to be clinically very important as the vast majority of hypothyroid patients do well on T4 supplementation alone and nearly all those who are still dissatisfied feel well again once T3 is added as well.All of the T4 produced by the thyroid undergoes peripheral deiodination in the liver to become T3 as T3 is the metabolically active thyroid horome.
