T3/T4 mix 100 tablets Bitiron Pharma Grade

Each tab has 50 mcg Levothyroxine (T4) and 12.5 mcg Liothyronine (T3).

Bitiron is a synthetically derived thyroid hormone replacement preparation. It consists of levothyroxine sodium (thyroxine, T4) and liothyronine sodium (triiodothyronine, T3) in a 4 to 1 ratio by weight. Liotrix was developed when it was believed that serum levels of both T4 and T3 were maintained by direct thyroidal secretion. It is now known that the thyroid gland secretes approximately ten times more T4 than T3 and that 80% of serum T3 is derived from deiodination of T4 in peripheral tissues.

Administration of levothyroxine alone is sufficient for maintaining serum T4 and T3 levels in most patients and combination hormone replacement therapy generally offers no therapeutic advantage. In fact, administration of T3 may result in supratherapeutic levels of T3.

Usage:

When used (off-label) to accelerate fat loss by bodybuilders and athletes, the typical protocol involves slow buildup of the dosage so that the body has ample time to adjust to the changing thyroid hormone levels.

An individual will generally start with a low dosage of 25-50 mcg, and will slowly increase the amount 25-50 mcg each day or two. The final dosage will usually be in the range of 100-150 mcg, and will rarely exceed 250 mcg.

It is important to remember that thyroid drugs are strong medications with significant side effect potential. Cautious individuals will be sure not to use excessive amounts of levothyroxine sodium, nor continue treatment for longer than eight weeks. It is also generally advised to also reduce the Synthroid dosage gradually at the conclusion of each cycle. This is usually accomplished by dropping the dosage by 25 mcg every second or third day. The focus here, again, is to help avoid any sudden change in hormone levels that might otherwise trigger side effects. Note that due to the slow acting nature of levothyroxine sodium, it may take several weeks or longer for the active drug to be fully eliminated from the body.
