Yeah, sure, absolutely.

But you can't always fix those things to the nth degree without wanting to at least experiment, especially when it comes to body composition stuff or energy levels.

So by making the one variable change at a time, you can say, look, let's do the experiment.

If your T is now 900...

And we haven't made a change during that period of time other than that T. And you're telling me, I don't really feel that much different.

My hypothesis is you have a pretty low density of androgen receptors, and they're largely saturated at 400.

And therefore, this isn't really the fix.

There's something else we need to be looking at.

Sorry, just to be clear, you were on hormone replacement therapy prior to?

No.

Okay.

Even though you were already in menopause.

So why did you decide to only go on hormone replacement therapy at the age of 57 when presumably you believed you were in menopause prior and didn't go on HRT?

You look like you've been at it for years.

And it sounds like you feel better as a result of it.

Yeah, that's an interesting point because, as you know, but maybe some of the listeners don't, testosterone is a regulated, scheduled drug hormone, whereas estrogen is not.

Estrogen can be prescribed without any DEA scheduling.

Testosterone is a schedule.

I believe it's a schedule for testosterone.

But that's an interesting point that you raise, right?
