the paragraphs below the charts echo my thoughts:
"Your ranges may change depending on what lab your doctor uses. For statistical purposes the typical male testosterone level is between 250ng/dl to 850 ng/dl. But… this is not a healthy range!
Reference ranges aren’t typically set by what is healthy and what is not. They are set by where 95% of the population lies. Do you honestly think 95% of the population is healthy? I didn’t think so. Unfortunately many doctors fall in to this line of thinking.
These ranges aren’t set for men interested in living a virile, energetic, ambitious quality of life. They are a cross section of men aged 20 to 100… many of them are sick and not healthy.
All the time I see men’s doctors giving them a testosterone reading of 275 ng/dl or so, and being told it’s “normal”, because it falls within range.
If this happens you have a couple options. You can kindly tell your doctor you have the testosterone level of a sick 90 year old, and maybe he or she will come around. "
