Liothyronine sodium (T3) is not an anabolic steroid. It’s a synthetic (man-made) version of
one of the two hormones made by the thyroid gland, triiodothyronine. It is used for treating
individuals who are hypothyroid (do not produce enough thyroid hormones). Thyroid
hormones increase the metabolism (activity) of all cells in the body. In the fetus, newborn
infant and child, thyroid hormones promote growth and development of tissues. In adults,
thyroid hormones help to maintain the function of the brain, the use of food by the body, and
body temperature. Bodybuilders are particularly attracted to this drug for its ability to burn off
body excess fat. Most often utilized during contest preparation, one can greatly decrease the
amount of stored fat without being forced to severely restrict calories. To this end
liothyronine sodium is commonly used in conjunction with Clenbuterol and can produce
extremely dramatic results.
