GNC Instaflex worked wonderfully for me. My knee pain and knee aches went away as soon as I started taking the pill.
I only took one pill per day. I did not need to use the anti-inflammatory prescribed by the Dr. For 3 days I have been out of Instaflex and my knee pain is coming back.
They are not inexpensive but they really worked for me.
I have more freedom of motion and flexibility than I have had in 10 years.
I am amazed and wonder what the secret ingredients are.
Additionally I took glucosamine and this never had any impact.
