testosterone levels med low after brachy 2 years ago

I have been searching for information about taking testosterone additives or whatever the market can offer because while i am 75 years old, and my brachy was 2 years ago, i tire faster than i did prior to Brachy.

my last psa was .7 and seems to always go lower every at 4 month checkup. I have no other problems
i do not take any pills for any ailments.

I feel my stamina should be better. I walk a great deal and exercise at least once a week playing intense racquetball for 1-1.5 hours, yet I find i run out of gas at the end of the hour or so.
i dont want to blame it on age.(just yet)

my doctor says my testosterone level is at med-low and just fine. I beg to differ, but before I start on any program that might increase my level of testosterone, I wonder if someone out there had gone through a testosterone therapy program and what if any changes they saw in themselves

thank you

At 75, a Testosterone injection won't make you 18 again.....

I'm only 51, and my HDR treatment was three years ago.

My T level was low, even prior to treatment. My PCP subscribed me T injections (at 48) and I was feeling 30; working out hard, playing basketball, etc. But my PSA doubled from 2.2 to 4.5 in that nine months.

A year ago (two years after my treatment) my T was below 200 and my PSA trended down so my uro (a specialist in the field) put me back on T injections. Last check it had risen to 380 or so.

I don't feel as good, strong, sexually aroused, etc. as I did back before my HDR when taking the T; but I think it helps and I'm in pretty good shape (need to lose 15 lbs).

I'd give it a try but do it under the care of someone with good credentials. You also might add some weight training and another day or two of racquet ball...
