Excellent
For times of intense academic activity, I recommend it without a doubt, I notice a great difference in concentration and assimilation of content that I am studying.

Well...
I hardly noticed the effects, maybe a little improvement in concentration is noticeable. For me it was not worth it.

The truth is that it has helped me not to need so much rest time and it makes me be a little more focused, so I perform better in less time.

Testing it.
I bought this product because of the favorable comments and because I usually like HSN products. Waiting for results, I think they are a lot of tablets, 4 a day but they have no taste.

Help in opposition.
I am taking it to prepare for competitive examinations and whether it is its effect, the combination with other supplements or the placebo effect, I feel a little more energy and focus.

I'm just getting started.
I bought the product, the pills are very large, difficult to digest, but I have not noticed their effect yet. I hope I can have good results.

Very good price and quality.
I already took it when it was launched and I liked it a lot. Now that they have lowered the price and changed the composition so you don't have to take so many capsules I think it's a great improvement. I really like this product.
