Human ageing reversed in ‘Holy Grail’ study

Main discussion, https://news.ycombinator.com/item?id=25163220 but I'm not sure if there is some new info here.

Note: They only show some increase in the length of the telomeres, that is an indirect indication of age reverse. So "Holy Grail" is overoverhype. It is not reproduced yet.

Huge if true.
