The average T conc of men my age (42) is around 500 ng/dl with a free T of 11 ng/dl. Ergo 50% of men my age have T levels lower than this.

And all of them should go on TRT to increase their levels to above 1000 ng/dl to get ‘there’?
The essence of testosterone replacement therapy is to restore T levels of hypogonadal men to levels of ‘normal’ men. Its not to optimize whatever.
