I have been taking rapamycin for many years now. It's obviously not ready for anywhere near the general public and is never something I'd suggest to someone at this point, but my own results have been wonderful and my blood panels and energy levels are great. If I had to guess, when properly used, this would probably add a full 5-10 years onto the lifespan of a lot of people. When combined with many other promising treatments, I think we could easily add 10-15 years onto most peoples' health+lifespans.
