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 pre-competition 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.
