The active ingredient in Euthyrox (T4) is Levothyroxine Sodium. Euthyrox (T4) is used to treat hypothyroidism, a condition in which the thyroid gland is underactive and so does not make enough thyroxine for the body's needs. Euthyrox is also used to treat thyroid cancer and diuse non-toxic goiter or Hashimoto's thyroiditis, conditions in which the thyroid gland becomes enlarged causing a swelling in the front of the neck.

Euthyrox (T4) is a synthetic thyroid hormone (Type T-4). Bodybuilders love this product for many reasons. Euthyrox (T4) is an excellent fat burner since your metabolism is greatly increased while being on it. You can afford to be a little sloppier on precontest dieting since it will still burn fat when you are taking in a lot of calories since your metabolism is going haywire. Step over Ripped Fuel, E/C/A stack, Thermodrine.

When taken with Clenbuterol, this is the single best fatburning combination that is available today (with the possible exception of DNP). It also helps to make steroids more effective since it is such a good aid for protein synthesis. Most people need to be careful to start with a low dosage, about 50 mcgs. per day and increase by about one tab or 50 mcg per day every 5-6 days. Make sure that you don't go over 100-200 mcg per day at the very most. On days that you take muliple tabs, divide the tabs evenly across the day (i.e. 200 mcg would be 4 doses of 50 mcg a piece spread evenly across the day.) You also need to make sure that you cycle down off this product as well to keep the thyroid functioning properly as well. Don't take for more than 5 weeks at a time as well. After doing a cycle of this drug, make sure you go at least 8 weeks before doing it again as to allow normal thyroid functioning to return.
