Hey guys been looking into my testosterone lvls lately. I'm 37 just don't have the drive for much of anything and when I do I pay for it on the back side. Anyway went to Dr the other day asked for them to test me. They only tested Free direct but these are the numbers. They did a free test lvl and it was 11.3 with a range of 8.7-25.1. With that I'm normal based on their info but my question is what does that number put me at in comparison to age. Don't think I'm at the bottom of this yet. Any insight would be useful.
