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.

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.
