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

It is working
I have to say I’m always very skeptical about these kinds of things. I did take the time to read reviews, then decided to go ahead and buy it to give it a try. It’s probably only been about two weeks and I have noticed a significant difference in my knees, elbows, etc. Whenever I would bend down, I would have a hard time standing back up, but now can do it with ease. I would highly recommend this product, and that’s not something I take lightly when giving a review. I can honestly say this will be a regiment that I will continue to stay on as a daily supplement.

Good quality
I’ve used it for a while. Seems like it does the job for me and I’d recommend it to some friends and they liked it too.

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!

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 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.
