Perhaps the most promising anti-aging drug is metformin.

Type 2 diabetics on metformin live 15% longer than non-diabetics. This is remarkable, considering how big a health disadvantage diabetes itself is.

Metformin seems to mimic fasting somehow, by interfering with mitochondrial function.

For more information, I refer you to David Sinclair's numerous discussions on this topic. He takes 1 gram of metformin per day, with his evening meal.

This is not medical advice.
