I take Tru Niagen NAD+ and set running PRs every year. Been doing it for four years. I am now within 20 seconds of the world record for the mile for my age. It just stops you from aging, and sets repair systems to maximum speed.
What dosage do you take?
Cheapest place to buy?
I did a NAD+ infusion. I thought it may have been a placebo affect but my wife noticed an improvement in movement and not as sleepy... weird.
It was a gift from one of my kids and I’m thinking about doing that again.
My first 2 bottles of Tru-Niagen were $30. Next time I tried to buy, the price was near $70, so I put that on hold.
