It worked for me
My knees would pop and creak loudly before I started to take these. I still have a little pop now and again but no discomfort anymore. I won’t stop taking these now

Good stuff
My bro in law uses this for his knee. He was walking like an old man (he’s 50) shuffling around. After about 2 weeks he’s walking normal. I tried it for my shoulder and I noticed a huge difference in my pain level after only 4-5 days. Now I have my husband trying it. Highly recommend!

I've been using TriFlex for a few years now and, I noticed less joint pain overall. Its a good product that works well.

Good but not the standard TriFlex
Simply, I have been taking Triflex for years. It keeps my knees stable from all the years of sports-related stress and injury. But the fast acting is not as effective for me as the original. The felt effect of the standard may take a few days to become effective, but once you are at that dosage, I don't feel the knee joint issues or pain. I recommend buying the original.
