There should be a clear distinction between using testosterone as a performance enhancing drug and as a replacement therapy. My brother suffered from worse hypogonadism that I did. With T levels near 150 he suffered from no sex drive, depression and fatigue. After replacement therapy his T levels were at 450 and all those things were repaired. I have also seen other men with severe low T levels and they will consistently tell you that they can't stand the low T levels.
I myself having been on testosterone ablation can tell you that quality of life increased with my T levels when I stopped the ablation ~ although mildly. Certainly drive returned and that was important to me.
It's true that synthetic testosterone makes your body reduce your natural production but if your body is naturally producing insufficient T levels then replacement is a blessing to the men who do it. You don't need to use the hormone levels necessary (sic) to race in the Tour de France but even low normal serum blood levels will help while not producing the side effects associated with PED's.
it's controversial especially when prostate cancer risks have been identified. But it needs to remain a decision to those who may be making a decision to use synthetics...
