There are plenty of things on the market right now for human anti aging. metformin is the only FDA approved drug for it and it is starting to get marketed more heavily towards this vs other uses.

David Sinclair has some interesting opinions and studies on human aging and supplements that show legit positive effects.

Then there was that one study out of Israel about the O2 chambers and how it added length to peoples telomeres.

Cool stuff is already here, just not super mainstream yet…
