Cytomel is not an anabolic steroid, but a thyroid gland hormone, triiodothyronine (T3). Clinically it is used to treat thyroid gland insufficiency, obesity, certain metabolic disorders, or fatigue. When given, Cytomel increases the metabolism of the patient. The result is increased cellular activity through more efficient and rapid use of fat, protein, and carbohydrates. Bodybuilders are attracted to this drug because of its ability to burn excess fat. You can lose significant amounts of fat without decreasing too much your calorie intake. Cytomel is used in combination with Clenbuterol, a combination that can have extreme effects on fat burning. This combination has become very popular in the last few years. Also, when thyroid hormones are taken in combination with steroids, an increase in their anabolic effect (due to more efficient use of nutrients) is observed.
