I've been using this product for a few years and I am happy with it
I only give this product 4 stars because it has to be something that really blows my socks off to get all 5 stars. I've been using this product for a  few years and I am happy with it. It is marketed for the body builders but this is not why I take them. I have been diagnosed with Maj. Depression and have been looking for alternatives and holistic methods of treating it rather than pharmaceutical psych meds. After taking a college course on genetics which taught me how the body uses DNA, amino acids, and proteins and where they came from I decided to supplement my lunch bag on the go diet (I'm a working student) with amino acids. I noticed a difference in my depression levels after about one month and the improvement has been sustained for a little over three years w/o the unwanted side effects of psych meds. I have looked but have been unable to find any good research on the use of amino acids to treat mental illness or possible side effects to taking large doses long term. With other life management  practices including outdoor cardio I have found this product very helpful with treating my depression.<br /><br />As far as building muscles, I can't really say. I do go to gym 4x days a week and perform 30 min of cardio and 30-45min resistance training and I mountain bike 2x weekly. I don't exercise to get big. I hit the gym to be a better biker and to manage weight gain. I also use other diet supplements. I used these for depression before the exercise routine. Since beginning exercise routine along with proper diet I have notice a difference in the gym but this can also be greatly due to technique. If your going for big I suppose they would work as well as any other protein product. The product I  like better though is Athlean-Rx. IT's a product produced by a guy name Jeff Cavalier who used to be the strength coach for the New York Mets. You can check out his web site at www.Athleen-x.com or look for him on YouTube.
