I started taking the Advanced Amino tablets because I had starved my brain of good chemicals. I also underwent surgery and was losing a lot of weight, now over a short period of time I am putting on bone mass and muscle mass it seems, not weight around my gut. I can only put it down too the Advanced Amino Tablet, so of course I am going to write about this product and now looking into another products Advanced Bio nutritionals make as it all seems very legitimate.
