Drugs or supplement regimes to reverse slowing down with aging? [View all]

[triron]

I am an ex-triathlete/mountain and xc runner who has slowed considerably; however I'm 73. I also had to get hip resurfacing
over 11 years ago and probably have moderate arthritis in the other hip (no significant symptoms yet however). Does anyone know
of drugs, supplements or any other interventions to reverse this to some degree? What, if anything, have been
your experiences with this?

I have tried serrapeptase, nattokinase, alkaline ionized water (which may have helped), arginine,
joint formulas (may help some), reduction of dietary sugar, fish oil, eating more fish, chicken and fresh vegetable and fruits
CoQ10, NAD+ and some other things with no more than potentially small beneficial effect.
