I think a lot of guys would get a positive indication from this test even though over time higher TRT doses would do nothing for their libido. As a one-time deal I get a nice boost from a little ester-less testosterone, but the benefits disappear if I do it daily. It's the usual "honeymoon" phenomenon.
The research generally shows that raising testosterone from low to normal can help libido, but raising it from normal doesn't do much...
With the OP's good lab numbers he needs to look elsewhere, such as at the missing upstream hormones. HCG is something to consider.
