And if I test someone in their 20s,

say I'm working them up for irregular periods, for example, I'll usually see levels around 30s to 40s for normal, these patients don't have PCOS.

So that's what I usually think of as like the physiologic level.

So that's kind of my goal.

I usually say my goal is 40 to 50 in a peri- or postmenopausal woman, nanograms per deciliter.

That's physiologic.

All right, so formulations.

So the formulations, if you're going to give the male product, right, men will usually use these products, either a tube or a gel.

They'll use one pump or one tube a day.

Now, you have to remember that the average male level, right, I just told you my goal is 40 to 50 nanograms per deciliter.

Well, men have like 400 to 800 nanograms per deciliter of testosterone.

So we're looking at one-tenth to one-twentieth, right?

Right.

That's our target.

So you want to be using one tenth.

We always say one tenth.

But the truth is, it's really one tenth to one twentieth.

And so I typically will tell people to get a PPD syringe, like a small one cc, one milliliter syringe, draw up between point three and point five of a tube of gel.

And then rub that into their inner thigh someplace where you don't want children to touch, right?

These are women who oftentimes have small children or where they don't mind hair growing because you can actually get hair growth at the site of where you place it.
