There is. Rapamycin and metformin. Both have anti-aging effects. But experiments to prove this on humans are hard to replicate as it involves studies of humans dying of old age. You'd need probably 20 years to run such a test. So they have shown this for mice and rats. BUT, there are side effects. Also I don't think these things reverse aging, they definitely slow it down though. I know rapamycin specifically works on MTOR which is identical to what happens with fasting. Too much rapamycin though isn't good.
