Hi Mike, <br> Welcome to the forum. <br> I wanted to write to urge you not to take any of the non-prescription HGH products --they are notoriously unreliable in terms of safety and quality. The best way to take HGH is by injection and your doctor should be the one to provide it if you try it. Your question is a good one for your doctor -- let your endocrinologist work with you to develop a treatment program. That's what you are paying him or her to do. You don't say how long you have been using the testosterone supplement but it can take 3-5 months to feel the full effects. Also, the different gels deliver different amounts of testosterone so you might ask to try Testim before deciding it's not working.
