    How Much Usable Energy Do you Have?

    For me, one of the biggest upsides to TRT has been better energy. However, I sometimes wonder if I should be content with the energy I have? I am currently 49. I get up pretty early - usually 5-6AM every day. I drink a decent amount of coffee, but am done by around 8AM. I use Natesto three...
