Jon V. reviewed Qualia Focus
If you are looking for a totally natural way to enhance your focus and concentration, I highly recommend Focus from NeuroHacker. I has totally helped my performance at work.
Focus experience
I noticed an increase in mental energy and overall mood beginning the first day of use, which I did not expect.
My new favourite cognitive supplement!
I love this stuff… I have only been taking it for 3 weeks now and have already noticed a big difference in my ability to stay focused and adapt to stress. My overall mood seems to have improved also!
Great for studying, has really helped me retain info.
I've tried other neutropics and this one actually has a feeling within a hour of taking it.
