Lab Result Help

Hi Guys,

I got my labs back and my test is 19.3 nmol/L. Apparently that’s ok for a 28 yr old male… what do you guys think? My doc said the ranges are between 12 and 28 nmol/L… and that my result is what he would expect.

I feel that is kinda low, plus I find it very hard to keep muscle.

any ides?
