Hello, Chap. I think your birth year coincides with mine. On to your question...
Before I get there, know that I am NOT a medical doctor. However, I do participate on testosterone forums (in fact, I belong to an excellent forum on yahoo which consists of men recovering from low testosterone. A few of the members there are medical doctors, as well.)
Libido is complicated, influenced by more than simply testosterone. That said, we should consider the actual results from your bloodwork.
