Euthyrox is a synthetic thyroid hormone (Type T-4). This product works by increasing the synthesis of protein, carbohydrates, and fats as well as RNA in the body thereby increasing your BMR (Basal Metabolic Rate).
Bodybuilders love this product for many reasons. This product 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.
When taken with clenbuterol, this is the single best fatburning combination that is available today. 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 25 mcgs per day and increase by about one tab or 25 mcgs per day every 5-6 days. Make sure that you don't go over 100 mcgs. per day at the very most. On days that you take muliple tabs, divide the tabs evenly across the day (i.e. 100 mcgs. would be 4 doses of 25 mcgs. apiece 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.
