Actually, a study on old rat muscles found NO more damage to repair proteins than in young rats—so the 'rusty' idea might be wrong. And there's zero evidence yet that the engineered 'super' protein works in humans.
There's disagreement
Studies point in different directions — there's no clear consensus yet.
The claim that muscle repair proteins get rusty with age isn't backed by research — in fact, old rat muscles show no more damage than young ones.
No research was found to support or refute the claims about the super protein itself — so we can't say if it works or not. But other research directly contradicts the idea that the normal protein gets 'rusty' with age. That study looked at old rat muscles and found no more damage to repair proteins than in young rats. So the notion that these proteins inevitably degrade with age doesn't hold up based on available evidence.
The super protein claims are unverified, but the rusty protein idea is actually contradicted by existing studies — so take the whole post with a grain of salt.
