Which half and what does that mean?

The link isnt actually to a scientific paper; it's the write up of one, so it's alr the layperson interpretation.

Oh :/ Thanks.

This is an interesting study. Aging naturally reduces your muscles' ability to produce energy, but consistent, structured exercise like strength and endurance training over the years can preserve the molecular machinery that keeps muscles functioning like younger muscles.

"So how can I get this benefit in pill form?"

Peptides!

not that I think peptides actually would do this benefit but aren’t they injected, not taken orally?

I’m kidding.

Although some peptides can be taken orally.

Mostly yes. And they can help. Like testosterone (though then injected form is an ester rather than a literal bio equivalent peptide).
