I actually gained muscle mass. My doc says it is unusal, but not unheard of. He said that my T levels were over the top for a normal male that the too much T had actually turned off the androgen receptors in my muscles. I had those "Olive Oyl" arms before HRT. 6 months in, I noticed that I was lifting heavy objects much easier than ever in my 58 year history at the time. I did get weaker during this past July's record heat without an air conditioner. But the strength I gained is coming back now. Most muscle gain is in my thighs.
This is actually welcome here. I need that to do the "male" things I still love to do. Wheeling that 225 lb telescope off and on the truck nightly at the dark sky site is easier than before. I own that telescope for 20 years now and used the same gear and method of loading and offloading during that time.
