T3 and T2 were compared to one another mano-a-mano in a clinical study comparing their effect on resting metabolism and oxidative capacity of metabolically active tissues (effects on muscle tissue, fat, brown adipose tissue, liver, and heart). T2 had a blatant dose-dependent effect which increased resting metabolism and oxidative capacity, exponentially increasing how much fat you can lose. Another study showed very promising and similar results, increased energy expenditure and oxidative capacity as a result of T2. It soon became evident that T2 has a very similar effect on lipid metabolism that T3 itself has.
Since that time, a bottle labeled androstenedione, a testosterone-producing supplement, was found in Mark McGwire's locker in 1998 and the baseball world was forever changed by the revelation of performance-enhancing drugs. With stringent drug testing and the threat of suspensions and fines, players are much more diligent about what they ingest to try to improve their performance particularly in the final weeks of the playoffs. But once the season is over, preparation -- including workouts, diets and supplementation -- begins for the opening of camps just a few months away in February.
