You can speak to that.

Okay.

So I have my own opinions, which are that—and I go back to the concept of developing insulin, which way back when we first started insulin, we gave insulin using bovine and— basically cow and pig pancreas, where we were able to administer insulin using those animal substances.

Of course, humans would get antibodies to those because they're not our own product.

So over time, as we got better and better and the science got better, we were able to recreate our own human insulin, and that's human recombinant insulin, and now that's just standard.

We would never think about giving another animal insulin to a human.

So the same is true, in my opinion, with creation of the human recombinant growth factors.

Well, Kristen, before we let you go, we have to talk about vitamin C because that was the one thing that you mentioned at the beginning that we haven't touched on yet.
