Thanks for your reply. I realize my case is complicated and I must rely on my doctor.<br> <br> I do have three basic questions:<br> <br> 1. How common is it for people to need two tubes of Testim to get satisfactory readings? It is my understanding from my doctor that Testim is very potent and he has never had a patient need two tubes. I have been finding the opposite based on by web research.<br> <br> 2. What kind of studies have been performed on the advantages of Testim vs. Androgen? I read the package inserts of both products and Androgel seemed to be more effective.<br> <br> 3. What factors have an impact of how well these products are able to raise T level? I do realize each individual is different<br> <br>
