Agreed. I started about age 29.. I had cancer at 28 and once I finally recovered from it, my test levels sat around 119 total. Never got much higher than that so I've been on trt ever since. My father still had levels close to 800 in his mid-50's though, he'll likely never need it. If you feel you might need it, get tested.. if your levels are still good no need to start bc it's usually for life once you do.
