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.

Highly recommend, it really works!
I've been taking fast acting TriFlex for about 6 months and it has worked for me. I have little to no pain in my right knee these days. I do a lot of stairs and elliptical so my knee really hurt for days. I highly recommend this product.
