I love his work (even though I know little more than what he says in interviews). I am also surprised it's not more widely known / applied. I am very skeptical of conspiracy-minded thinking, so I'd much rather assume his and his team's work hasn't reached escape velocity from obscurity. Especially with larger industries, it takes time and significant breakthroughs to become "a household name", so to speak.

They are working on getting in vivo studies going from what I remember - it's going to take a positive result in a trial on real patients to get attention - that's just how medicine works. You have to show it actually improves longevity and/or patient quality of life before anyone has a reason to care.
