"I’ve been using injectable NAD for years, but honestly? It was a faff. Measuring doses, packing syringes for travel, and praying my glass vial didn’t smash in my bag. Then I found Vaion+ NAD PEN, and problem solved. The pen is so easy to use, refill when needed, and throw in my bag without a second thought. And the best part? This is pure NAD—you feel it. More energy, clearer mind, and just that all-round healthy, balanced feeling. I never miss a day."
