Thyroxine is the main hormone of the thyroid gland. It is biologically inactive, using a special enzyme in the body turns into a more active form - triiodothyronine. Thyroxin is used in medicine for the treatment of hypothyroidism, in addition, thyroxin is widely used in bodybuilding as a means for losing weight.
T3 is often used in BB instead of thyroxin, according to the mechanism of action they are almost identical.
The thyroid gland secretes mainly T4 (thyroxine) - by itself, this hormone has a weak biological activity, but in tissues, with the help of enzymes it is converted into a more active form T3. T3, in turn, has the main biological effect. Thus, T4 can be considered a prohormone, which in the tissues turns into the main hormone T3.
Thyroxin burns fat by improving metabolism, maintaining heat circulation, stimulating the central nervous system and reducing appetite.
Its popularity has decreased recently due to the negative effect on the heart, thyroxin has an adrenaline-like effect, causing the heart to beat faster, and with it causes a feeling of excitement and anxiety, which are not very well tolerated.
To prevent seizures, it is recommended to take Ketotifen in the second part of a day or at bedtime.
