No difference
I'm a masters student, plugging through endless papers / lectures. Gave this a product a try hoping for a boost in my focus, alertness, and awareness. At $54 I assumed this was going to be a product of quality and most of all legitimate. I assumed wrong. I've been taking it now for over three months and so far I received no noticeable benefit.
