Tyler R. reviewed Qualia Mind
I got this originally for myself but after realizing there's a caffeine I gifted the bottle to my father. He's enjoying it and tells me it works great.
Great product
Seems to work really well when ready or studying. The only thing I would say is that I would rather the caffeine free one next time because I seem to have a lot of good energy and I want to move, so this would be better for the gym.
