OP, you have answered your own question more or less. It is only today that we live in an age were both supplements and the necessary knowledge to use them is available.* It is only now that supplements become available that may have very weak age-retarding effects (or not).*
Apart from that there are no miraculous supplements that I know of anyway, so you will hardly find any individuals that significantly slowed down aging using supplements.
IMHO it's way too easy to do harm with supplements and there are not enough hardcore life extensionists to asses and quantify the possible effects supplements might have.
* Maybe I'm wrong but what supplements were available back in the day? PBN (the spintrap) in the 90s? Metformin? Melatonin? alpha-lipoic acid? High dose antioxidants? Most of those interventions are unlikely to have a (significant) positive effect anyway. What about correct dosing, was this common knowledge back then?
Assuming you started in the 90s with your supplement regimen, you were lucky and it did no harm *and* worked in some way. To show any visible and appreciable change after those 20 years (slowing of aging), the regime would need to be in the ballpark of at least ~25% max life span extension (so you'd age 15 years in 20 years). There is no such magic pill, not even today.
I have noticed that spin traps do not seem too popular here for some reason. Or anywhere.
I have also noticed that googling "Dr. Peter Proctor" provides some pretty entertaining results. He has a delightful house, apparently.
I am not even sure if they work at all (
note the recent failure of the main metabolite of PBN) and if they did it would be difficult to notice (IIRC 3-5% mean/max life span extension in some early studies on rodents) for outsiders.
