Description:

Levothyroxine 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but was withdrawn due to cardiac side effects.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.

Application:

T4 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.

Levothyroxine sodium 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.

Usage and Dosage:

Users discovered T3 to be a better choice over T4 when using Thyroid drugs during Cyclic Ketogenic Diets.T4 must be used in much higher doses to be as effective as T3. Subjects found they needed to use

a dosage of 300 mcg/day to achieve the same results as 25-100 mcg/day of T3 (Cytomel).
