honestly once hyaluronic acid is in your system it makes that other stuff look like it does nothing. I kept hearing a popping in my achilles when I would stand up and after about 3 weeks taking it, it completely went away. An old school bodybuilder that went to my gym that has won 13 shows told me about it. He said his knees sounded like packaging bubbles being popped, and this took care of it. Real knowledgeable dude so I tried it and was happy.
