Hey David, thank you for your comment. We're sorry to hear that you did not enjoy the product and we definitely understand your point. However, we'd like to point out explicitely that the effect of the FSB is not to be compared to the effect of a coffee, simply because they aren't in the same category. A strong coffee is a short-lived energy kickstarter, but the Flow State Booster is a prolonging focus-supporter. Focusing can be difficult when you're loaded with caffeine, which is why we intentionally use little caffeine in the Flow State Booster. We hope that we could clarify the misunderstanding. If you still have questions or remarks, feel free to reach out to us!
