Both - No I haven't had my off levels tested off, but I have thought about this a lot from the improvement to my mental clarity , stamina energy level during the day after a long hard day at work, my libido sexual health and the ability to manage body weight/ fat effectively. Im 45 years old and as you know time flies I can't imagine my self in my 50's and 60's with out trt at this point. My father is 78 and his test level is around 280 ng and the dr still doesn't want him to be on it. I refuse to be one of those older people who have to nap 3 hrs a day in the afternoon cant sleep at night more than 3 hrs at a time, and can't think straight due to low T levels ( not that other things cant cause cognitive issues) Finally of course I want the advantage for bodybuilding but even if I wasn't into lifting when I'm older and just cycled or had another hobby to stay in shape I would still want to do it, seems there are too many pros with a few cons at this point. I believe in the future this will be a pretty much standard thing for older men. I believe I would be putting off the inevitable....
