The wide range of collagen products does not make it easy for the user to choose one of them. My choice fell on "ELASTEN". Priced in the upper range, studies and statements of other users promise complete satisfaction. The interest of the pharmacy staff in my experiences with this product led me to keep this diary. I could not foresee that this would develop into a valuable experience report, also for others. Because, "ELASTEN" gave me not only external, but also internal improvements. With the first bottle of this product my new life began. These insights are too valuable not to share.
