Fantastic!
Never thought I needed something like this, but after two years, decided to try it. Honestly, it’s some of the best sleep I’ve ever had and I wake up feeling rested. Love it!

Works but not really
So because I take Project-1 Pro in the last afternoon 4:30-5:30pm. Took core-21 for about 3 days no matter if half an hour or 1-2 hours before I sleep I still don’t sleep until few hours after that. However I’m in a deep sleep and feel rested the next day. To me it’s okay for sleep and recovery.

Solid supplement!
Be advised... read the instructions first. ha ha.
First time taking it, I took it mid day and it took me out. Fell asleep on the couch for a few hours... Turns out, you're supposed to take it at night. All in all, it's a phenomenal supplement! highly recommend.
