They work like a dream!
Get a minimum of 90- minutes of REM sleep when I take these.

Works well, better mental clarity this week 100%
Will be buying again. Works epic. Thanks guys
Great product, especially since every other NAD+ supplement is over $50...completely worth the value.
Super rad for being sick. Def made me feel better in days.
Every single time I fall asleep within a MAX of 30-minutes. Get a solid 7 hours every single night and STAY asleep.
Works fantastic as a nootropic for me.
