But the hydroxyproline is not a precursor for your incorporation in your own collagen.

But it might have a stimulatory effect or a signaling effect, but we don't know.

I mean, again, what does the muscle see?

What does those other tissues see?

What does the synovium see?

The only thing that, I mean, to be honest, I mean, about, I think, four or five years ago, I think that we were the first to assess the synthesis rate of all the proteins in and around the knee.

So what we did is we infused people before they underwent full knee surgery

And we measured the synthesis rate of muscle, cartilage, sovis, synovium, menisci, the ACL, the PCL.

So everything there was really funny because normally we take a muscle biopsy and then we have 100, 150 milligrams of muscle and we're completely happy.

And then we have to measure all these different things in that small amount of muscle.

Now you're standing in the surgery room.

and you're getting a whole mixed grill.

I mean, I'm getting a meniscus.

I'm getting an ACL and PCL.

I'm getting all this tissue, and I can measure this and this and this.

Now we have a whole spectrum of all the tissues in and around the knee, and the synthesis rates were almost all in the same ballpark as muscle.

And I thought that was already, for me, the first step towards nutrition in these tissues because the regenerative capacity of these tissues is higher than anticipated.

Yeah, so we know that, especially from abuse, of course, that the growth hormone has, in combination with, for example, anabolic steroids, can help you with the connective tissue protein synthesis and stuff like that.

So, yeah.

Not sure whether to suggest that you have to combine it with collagen peptides or anything like that.
