Some relief
My knees seem to feel better but not quite as good as I was hoping for. I’ve only been taking it for 10 days so hopefully they will get better.

it didn't do the trick!
I am very disappointed with it. I need to return the unopened bottle for something else. Over the years, i have introduced many friends to the TriFlex brand and they have referred their friends-but not this time.
