TSH, t3, and rt3. In hypothyroidism, TSH will be in the low normal to high ranges. In good functioning thyroids, TSH will be low.

Before using a Cytomel (T3) supplement, it might be possible to solve the problem with diet alone. A piece of fruit or glass of juice or milk between meals, and adequate animal protein (or potato protein) in the diet is sometimes enough to allow the liver to produce the hormone. If Cytomel is used, it is efficient to approximate the physiological rate of T3 formation, by nibbling one (10 to 25 mcg) tablet during the day. When a large amount is taken at one time, the liver is likely to convert much of it to the inactive reverse T3 form, in a normal defensive response.
Women normally have less active livers than men do. Estrogen can have a directly toxic effect on the liver, but the normal reason for the difference is probably that temperature and thyroid function strongly influence the liver, and are generally lower in women than in men. Estrogen inhibits the secretion of hormone by the thyroid gland itself, probably by inhibiting the proteolytic enzymes which dissolves the colloid. Progesterone has the opposite effect, promoting the release of the hormones from the gland. At puberty, in pregnancy, and at menopause, the thyroid gland often enlarges, probably as a result of estrogen dominance.
Thyroid function stimulates the liver to inactivate estrogen for secretion, so estrogen dominance can create a viscous circle, in which estrogen (or deficient progesterone) blocks thyroid secretion, causing the liver to allow estrogen to accumulate to even higher levels. Progesterone (even one dose, in some cases) can break the cycle. However, if the gland is very big, one person can experience a few months of hyperthyroidism, as the gland returns to normal. It is better to allow the enlarged gland to shrink more slowly by using a thyroid supplement. If an enlarged gland does begin to secrete too much thyroid hormone, it can be controlled with tablets of propylthiouracil, or even raw cabbage or cabbage juice, and cysteine rich meats, including liver.
Besides fasting, or chronic protein deficiency, the common causes of hypothyroidism are excessive stress or “aerobic” (i.e., anaerobic) exercise, and diets containing beans, lentils, nuts, unsaturated fats (including carotene), and undercooked broccoli, cauliflower, cabbage, and mustard greens. Many health conscious people become hypothyroid with a synergistic program of undercooked vegetables, legumes instead of animal proteins, oils instead of butter, carotene instead of vitamin A, and breathless exercise instead of stimulating life."
Time is passing so quickly. Right now, I feel like complaining to Einstein. Whether time is slow or fast depends on perception. Relativity theory is so romantic. And so sad.
