People like Cliff High are deep into the rabbit hold of the research and self experimentation. It shows ~X2 lifespan extension when fed to adult rats who are genetically programmed for death.
The basic lowdown is that they are buckyballs, the perfect size to fit into many parts of you body on a molecular level. And they are greedy for things like free radicals. Massively greedy. The exact method(s) by which they extend lifespan is mostly speculated at this time but I'm putting myself on a steady high dosing of the stuff suspended in coconut oil (it has to be stirred in a fat for two weeks to make it bio-available). My setup should make 1 liter every two weeks, more than enough to share with the people in my life who need it the most.
