Oof, testosterone comes with a ton of downsides (your body will stop making its own). We are really careful about people who start on testosterone replacement therapy, as it's a lifelong thing.
What’s interesting is that Bryan himself claimed to have stopped TRT and was able to restore his levels to baseline levels. I have clinical hypogonadism so I was probably going to need lifelong TRT anyway. My LH and FSH were normal but testosterone and estradiol were both low. It was a sudden drop too.
