Good product, and caffeine free, that's a plus.
I just got this product and started it so I cannot report actual results until I have some time to monitor its efficacy. I have high expectations however.
This product seems to be working as far as improving memory, focus and alertness in the long run. And most important of all, without the side effects of caffeine. As well as not affecting my sleep. Definetly recommending this product.
Excelente producto
