After seeing the video on Advanced Amino, all the benefit points made seemed to be directed at me. I ordered a three month supply initially as I feel no product can get results sooner. Since that time I have ordered 3 more bottles, successfully referred 4 friends who are athletes, and my results have been fantastic. I am 65 years old, formerly a racquetball player and started back on outdoor sports that included tennis and paddle tennis at the beach. Warm weather has made paddle tennis the primary activity at this time. My goals, using Advanced Amino, were healing of a nagging high hamstring injury (like the doc in the video) and to refine my body with the addition of muscle mass while transforming my overall shape. On days I play sports I take 5 tablets first thing in the morning before the sport, and then 5 tablets prior to sleep so 10 total. On days I do not play a sport, I take 5 in the morning when I wake up. I have gone down form 215 to 210lbs., my fitness is better than ever, my hamstring is no longer an issue (but I also get massage as well) and I just have the overall feeling of better fitness and wellness. I play my son who is 30 years my junior and I can keep up with him for 90 minutes or more. (He still wins most the time. I am on the soapbox about Advanced Amino. One of the friends I referred is a former Czech Olympic skier, older now but still a great athlete, he loves it too. I have 1.5 bottles remaining but will be reordering very soon. Combine a sensible diet, with sensible exercise and add Advanced Amino in your regime and you have a winning combination for being in great shape.
