i have a very powerful concentration, storage and recall of information, i study easily and w/o any effort with this raw pituitary pill, i study many hours daily, 6 or more and my concentration is excellent and most importantly the recall is95% , you may have a little warm feeling in your face but it is for a few seconds, past that and you will get a photographic memory, i enjoy this product. carlos
The capsules seem to be of high concentration. So I have to take half at a time, rather that a whole one, other wise I get a headache. But I think is a very good product, from a highly natural source. I will continue taking it for sure!
