Harry S. reviewed Qualia Focus | Beta Tester
Good. I didn't notice a major difference. I liked the extra energy and noticed some calmness.
Good for focus and productivity
Effects are subtle, but consistent. I'd describe them as a general increase in clarity and ease of focus for about 4-6 hours after taking before steadily winding down with no noticeable crash.
Great mental boost
Felt more clarity and alertness during the entire day using this product!
