I'm curious as to know when is this technology available. That and it comes in two forms, injection or pill. Just like how our body ages due to the hormone(cell signaling molecules) inside the blood stream that upshifts or downshifts the gene expression. We counteract with our own artificial cell signaling molecules to downshift or upshift this particular gene expression back to its place.

Long story short, by enabling the Yamanaka factors(transcription factors) with the cell signaling molecules to express these genes for a few days we could theoretically rejuvenate our cells to a younger age. We probably can't jump our age from 80 to 6, but we could go from 80 to 30, that is after the puberty has done its work.

So I want to know how long it would take for this to be available, last time I checked the SALK research they promised to be out in 10 years, and it was back in 2016. And this is of course with no side effects in messing up the epigenome or turning into cancer. Let me know, thanks

I believe I have an answer, check out this thread.
