I am 76 years old and was told I couldn't build new muscle . With the sudden passing of my wife of 46 years I decided to get off the couch and get back in shape. I started going to the gym 3 times a week ,taking some fat loss supplements and cleaned up my eating habits. Fat was coming off fast but wasn't see the gains I was looking for . Found Advanced Amino and it was game on. My personal Trainer at the gym put me on their body scan machine at the start of my effort and again 3 months later. I have had a net loss of 36 pounds of fat (lose skin all over my belly, but very little fat. Abs are starting to show. The real thrill was when she in formed me that I had also gained back over 10 lbs of lean muscle mass and could expect better results by eating more. Long story short, I'm very pleased with Advanced Amino. The pills are good but the powder mixed with cranberry juice is excellent.
