Description: T4 L-Thyroxine in a pressed tablet application. T4 is also known as L-Thyroxine T4 and is one of two primary hormones your thyroid produces, the other being triiodothyronine, or T3, although T4 makes up 90 percent of thyroid hormone. Every cell in your body depends upon thyroid hormones to regulate their metabolic function. Thyroid medication is frequently used by bodybuilders getting ready for a competition to lose excess fat by speeding up their basal metabolic rate and help them get 'cut,' or produce maximum muscle definition. Although the thyroid hormone T3 is more popular for this purpose, T4 may lead to increased muscle retention and improve the effects of growth hormone in weightlifters who are also taking growth hormone.
