Drug class: Synthetic thyroid hormone

Common names: Levothyroxine, T-4.



Levothyroxine – also known as T4 – is a naturally occurring hormone produced by the thyroid gland.
Levothyroxine is the thyroid hormone, which is produced directly by the thyroid gland, whereas the thyroid hormone liothyronine (T3) is produced in the body by enzymatic conversion of the thyroid hormone levothyroxine.

The task of thyroid hormones in the body consists in the regulation of burning fat, carbohydrates and protein. This means thyroid hormones are responsible for the amount of the metabolic turnover, which is burned in the resting state during a given period of time.
If, therefore, the thyroid hormone level is low, the basic turnover of fat, carbohydrate and protein burning is also low. If the mirror of the thyroid hormones rises, so does the combustion.

Since thyroid function is usually due to the thyroid gland producing too small amounts of thyroid hormone levothyroxine (T4), a thyroid hormone preparation with levothyroxine (T4) is almost always used.
The thyroid hormone liothyronine (T3) is used in the rarer cases, for example, when the conversion of the thyroid hormone levothyroxine (T4) into the thyroid hormone liothyronine (T3) is disturbed.

Bodybuilders occasionally use the thyroid gland hormone levothyroxine during the mass phase, to increase the metabolic turnover and burn more calories.
If you would eat mainly fat fast and junk food, you would not become fat.
The meaning of compensating the negative effects of false nutrition with the help of thyroid hormones is, however, more than questionable.

Furthermore, the protein metabolism is stimulated by thyroid hormones, which can lead to an increased protein synthesis with simultaneous high protein supply in combination with anabolic steroids.

Bodybuilders often take protein preparations and / or clenbuterol with the use of thyroid hormones to counteract the muscle breakdown. In order to provide absolute muscle control, male users also use Androge.

The use of levothyroxine (T4) often involves the addition of iodine. Since it is most effective to keep your thyroid hormone level at the natural upper limit in a diet, it is advisable to have its values determined beforehand by a physician.
