In terms of being a productive non-assholic member of society and not being overly aggressive or engaging in harmful behavior, risky behavior, what's the pro and con case for that in your mind?

Yeah, the most complicating thing, if I could wave a magic wand, wave one magic wand in medicine right now, what would I have?

I would have a PSA equivalent for breast cancer.

Come back to why that would be a game-changing solution down the line.

The second thing, which would not be nearly as important, would be I would love to have an assay to measure androgen receptor density.

Because what we can't, we tell all our patients this, they look at us like, just measure it.

And I'm like, no, no, you don't understand.

We don't have a test for it.

And they're like, how do you not have a test for this?

I mean, I guess you could.

Is there a commercial test for that?

I mean, you can do that in the lab.

Someone should develop a CLIA-approved assay for this.

But the point I really want to make is, why is it that one guy can have a testosterone of 400 and feel totally fine, and another guy can have a testosterone of 400 and feel totally depleted?

And if you took both of those guys up to 1,000, the first guy would be like, I don't feel any better.

And the second guy would be like, you've changed my life.

No, you can't, but you can just change one variable at a time.

Typically, tea won't fix a lot of those things.

The most obvious things you try to fix are sleep, nutrition, and exercise.

Regardless of what his testosterone level is, if it's 400, which is very low, especially if his free testosterone is equivalently low, and he's got these vague symptoms, it's like, well, look, if you're not sleeping well, eating well, and exercising well, let's fix those first.
