Typically normal testosterone ranges from 300-1100. Typically, I would like to see the total testosterone above 500.
The normal value for the free testosterone ranges from 80-300.
I think that with these values, you may benefit from testosterone therapy, which can certainly improve the libido. You may want to discuss with your physician the possibility of AndroGel or a similar testosterone replacement product.
Followup with your personal physician is essential.
