Liz Parrish has done the Klotho gene therapy. As well as Telomere, PGC-1α and myostatin gene therapies.
She “looks” pretty darned healthy to me from the many videos she is in. I think she is 54 or 55 now so about 10 years of data should be available from her experience.
Unfortunately n of 1 doesn’t mean anything, and I bet she does as much facial / skin work as Bryan Johnson.
And yet we are all here doing our own N=1 personal studies.
Some would argue that N=1 studies are important when attempting to move something forward, like increasing health span.
She is not doing this in a vacuum
