This information about Klotho is not new. Do a search on YouTube, and you can find many videos on this going back more than a year. Here is one video that I like, and it even shows how to increase Klotho naturally (hint: exercise, emphasis on resistance training over endurance, but both work): https://youtu.be/4xQ1D-0vj4M?si=MbY8vZrchotAWeck
No, klotho itself isn’t... What is new is using CRISPER to re-write a benign virus to get it into both the blood stream and into the brain so that cells can produce elevated amounts of it themselves...
Before was just supplementation and experiments.
