Gray Iron has no medical degree. I'm just a fitness guy whose been at it a long time and reads a lot. That said, I am skeptical about hormone therapies I hear about. Is there some miracle pill to stop aging just around the corner? Is it already here? Like I said, I'm skeptical. My advice: Until legitimate studies are concluded and scientists say this stuff is safe and that it works, forget it.
Bottom line: Eat right, regularly hit the weights, and unless under a good doctor's care -- don't even think about messing with hormones.
Here is a report on a study (source: Journal of the American Medical Association) that seems to point out deficiencies in testosterone therapy even in men tested with "low normal testosterone levels" and would supposedly benefit.
