Started taking Advanced Amino right after my back surgery. I took 5 tablets a day. 5 days after my surgery I was at my doctors office, he checked my back and was amazed. I had 9 staples at my surgery site. I was completely healed. I told my doctor I was taking Advanced Amino, he was totally blown away by my results. I contacted my surgeon and had my staples removed 3 days later, my Orthopedic surgeon was also amazed. I am 4 weeks since surgery and now starting P/T.
