But when you look at the studies, like there was that one study that was done on women where they took just the centromino acid supplement, compared it to a scoop of whey protein and how they got –

So it's the primary driver for muscle protein synthesis.

So muscle protein synthesis is what we measured if you're building muscle or building tissue.

It's the leucine that triggers it.

Now, you want the amino acids in there because when it's triggered, then it uses those amino acids to do what it needs to do.

But it's the leucine that basically pulls the trigger.

Because they're expensive.

So Keon's is 40%.

40% is from leucine.

And then the rest of the amino acids are in there.

So this will make a difference.

So if you've tried essential amino acids before, you're like, didn't do much, try theirs and see what happens.

And that's the one that we started taking because we had the interview with the founder.

It made a big difference.
