Taking testosterone at doses of 600-800 ng/dL is augmenting, not replacing, hormone levels for many individuals.

“So let's say that somebody decides they're not concerned with fertility, or they're going to bank sperm, or they already have kids, or they're going to defer on this issue of wanting to have kids, my understanding is that nowadays, a lot of people are using testosterone-- let's not even call it replacement therapy, because some of these people have 600, 700, or even 800 nanogram per deciliter read. So they're not replacing anything that is diminished. They're just trying to augment what's already there-- increase what's already there.”
