Tested for and found to have low testosterone 2 or 3 years ago. Started taking IM testosterone once every two weeks( much cheaper than the patches).
I have seen a great improvement in my overall attitude, energy level and response to training. I have probably been hypo-T most of my life unable to gain significant strength or muscle mass. I now find that my strength training is worth it with continuing gradual increase in size and strength. This has carried over to my riding.
