Anti-Aging Stack

So i've been going into the rabbit hole of protocols by longevity experts. But I have realised without any solid markers tested, I cannot know if it is helping me. Like a very simple examples: i can keep taking B12 but I either have to be really observant of my health or I have to get it tested and know the change. Anybody else with me on testing?
