By Dr. Zane Hauck, ZRT Laboratory Growing up, I never thought of myself as a runner, or really a good athlete in general. I played every sport possible as a kid, but I was never great and didn’t play high school sports. As an adult, I started playing team sports again and eventually was convinced to run a 5k.

Posted by Ben White on

Low testosterone in older men, often referred to as “male menopause” or even “andropause” is fairly well known — and testosterone replacement therapy in this age group has not been without its share of controversy, particularly with respect to heart health. Proper testing and dosing are all-important, as well as understanding a man’s physiology and all the factors that affect testosterone levels. For example, when giving testosterone transdermally it is critical to use testing methods such as dried blood spot or saliva to properly assess absorption of testosterone into the body, avoiding the problem of overdosing to achieve “normal” serum levels. But while...
