Well yeah ... Testosterone cuts incidence of metabolic syndrome

A new study shows that testosterone therapy can help middle aged and older men (with testosterone deficiency) to reverse many of the markers of metabolic syndrome. Metabolic syndrome is diagnosed as the concurrence of abdominal fat, high blood triglycerides (fats), high blood sugar and high blood pressure.

Of the 47 men who met the criteria for a diagnosis of the metabolic syndrome at the beginning of the study, 36 (77 percent) no longer had the diagnosis after 2 years of treatment, the authors reported. Furthermore, liver function significantly improved during the first 12 to 18 months of therapy and stabilized for the remainder of the study period. Treatment also greatly decreased blood levels of C-reactive protein, a measure of inflammation that is linked to increased risk of cardiovascular disease. “We conclude that testosterone therapy in men with testosterone deficiency can largely improve or even remedy the metabolic syndrome, which will most likely decrease their risk of diabetes and cardiovascular disease,” Saad said.

What wasn't noted was that exercise could provide all of these benefits as well (operating through basically the same pathway). Studies show that lifting heavy weights, using multi-joint lifts like squats, cleans and deadlifts, over several sets results in increased natural testosterone production as the body responds to the stress of this training.

Here's a question with an obvious answer. What would be healthier, to raise testosterone levels through exercise or to take an external replacement?
