I bought these refill cartridges after finishing the first set that came with my NAD pen kit. The replacement process is extremely simple and the cartridges fit perfectly into the device. What I like most about the refill system is that you don’t have to purchase a completely new kit each time. After several weeks of maintaining a regular routine, I’ve noticed that my energy throughout the day feels more stable, especially during busy workdays. Considering the price compared to clinic NAD treatments, this feels like a much more practical option.

I originally purchased the NAD pen kit a few months ago and these refill cartridges make it very easy to continue the routine. The cartridges are simple to install and the quality feels very consistent. I had previously looked into NAD therapy at clinics but the cost and time commitment were quite high. With these refills I can continue the same routine at home, which is much more convenient.
