A great quality ZMA product by Beverly International. I had amazing results with this product. My sleeping quality shot throught the roof. I was sleeping deeper and longer at night. The 3 capsule protocol is spot on for effectiveness. The price is decent, maybe a tad on the pricey side but well worth the value. One of the best ZMA products that i have tried so far. I would highly recommned to anyone that wants to increase the quality of their sleep immensely.
