Unlimited Bio claims a single gene therapy injection builds muscle and extends lifespan without exercise, showing a 50% lifespan increase in mice. But the science is unclear, side effects are undisclosed, and the promotional pitch raises questions about whether it actually works.

Just a single shot of this gene therapy that you also have on your tables can grow your muscles for years, even without going to the gym. But don't put it in your coffee, please. Again. So we developed— Is this going to make me younger? This? No, it's going to make you stronger. Stronger, stronger. Stronger. Yeah. Oh, I'm strong enough.
Like, how is this process possible, first of all? And the second question is, is there a business model like you subscribe to? Because this is longevity.
2 questions. Side effects and is it worth it? Right. Yeah.
Yeah, sure.
So you can see how this works on these mice. It's too similar.
But what happened to that mouse after?
Exactly, those mice, I don't know, but they upregulating this gene, the extended mice lifespan up to 50%. You're not telling us what's the negative side effect.
