No interest in PQQ I see.

Hi Keith. Thanks for commenting. I’m not aware of enough PQQ studies in humans to support its inclusion with the other geroprotectors in this list. If you know of multiple peer-reviewed, double-blind, placebo-controlled studies that demonstrate a notable magnitude of geroprotective effect in humans from PQQ supplementation, I’d value being directed to them.
