Levothyroxine (INN, USAN) or L-thyroxine is a synthetic thyroid hormone that is chemically identical to thyroxine (T4), which is naturally secreted by the follicular cells of the thyroid gland. It is used to treat thyroid hormone deficiency, and occasionally to prevent the recurrence of thyroid cancer. Like its naturally secreted counterpart, levothyroxine is a chiral compound in the L-form. The related drug dextrothyroxine (D-thyroxine) was used in the past as a treatment for hypercholesterolemia (elevated cholesterol levels) but was withdrawn due to cardiac side effects.
Levothyroxine is typically used to treat hypothyroidism, and is the treatment of choice for patients with hypothyroidism, who often require lifelong thyroid hormone therapy. It may also be used to treat goiter
via its ability to lower thyroid-stimulating hormone (TSH), a hormone that is considered goiter-inducing. Levothyroxine is also used as interventional therapy in patients with nodular thyroid disease or thyroid cancer to suppress thyroid-stimulating hormone (TSH) secretion. In 1992, President George H.W. Bush told television host Larry King that he had been prescribed levothyroxine as part of a treatment regimen for Graves' disease.
Side effects: This medication should not be used for weight loss. Normal doses of this medication will
not work for weight loss, and large doses of this medication may cause serious, possibly fatal side
effects, especially when taken with diet pills.
T4/L-Thyroxine is pro-hormone, which your body converts into T3 at necessary rate only and thus
it could be considered as much milder and safer drug than T3.
L-Thyroxine is an excellent fat burner since your metabolism is greatly increased while being on it.
You can afford to be a little sloppier on pre-contest dieting since it will still burn fat when you are
taking in a lot of calories since your metabolism is going haywire.
L-Thyroxine is widely used by bodybuilders and fitness addicts on precompetition cycle in order to
get relief, also used by overweighed people to reduce weight. It increases metabolism and produces
general stimulating effects. However, this substance should be used wisely.
