Ashish K. reviewed Qualia Mind
This is by far the best product to provide day long focus and drive without being "too much" the way many other products feel.
The best that there is
I have tried a number of supplements - quite a number - before I stumbled on Qualia Mind. Some of them were excellent, but they don't hold a candle to Mind. This is absolutely the best; I highly recommend it for memory, focus, and - most especially - drive.
