After stopping and starting a couple times with Advanced Amino, I finally have stuck with it and been more consistent with taking this supplement . My hopes were to see increases in not just strength, but energy, stamina and balance/stability. I can say that this has definitely helped improve all three areas with even one unexpected benefit - a marked decrease in chronic low back pain and sciatica-type symptoms. I'm glad I gave this another go! You just don't know how your body will respond to a given supplement, or the quality of the product and company, but I can say after doing a fair bit of due diligence and following Advanced Bionutritionals for some time now, and how conservative and genuine their marketing is compared to other of their peers, I believe I've found the company whose products I will continue to use for the foreseeable future.
