Just wrapped up my 44 day run of Universal Nutrition's Animal Flex Joint Support System. I have a history of joint problems stemming from lifting (particularly in the elbows and left knee), and despite consuming copious amounts of Fish Oil, Chondroitin and Glucosamine, there has always been a great deal of discomfort (when warming up it feels like my elbows are on fire, but as the blood gets going, the pain subsides). Looking for alternatives, I tried Orange Triad and Super Cissus RX, but they were actually less effective than the aforementioned Chon and Gluco supplements. Finally, after hearing some good things about Animal Flex, I decided to give it a try. In each can, there are 44 individually wrapped servings of animal flex, consisting of approximately 8 tablets. If your averse to pill popping, this product is definately not for you. I started to notice a noticeable reduction in pain after approximately one week, and by the end of the cycle, I would say there has been a marked improvement in overall joint health. While there is still some pain when lifting, it is not NEARLY as bad as before (probably an 80% reduction if I had to put a number on it). As an added bonus, my knee has stopped clicking when doing squats. Overall, I would give the product a solid 9/10. It is far and away the best joint support formula I have tried, but the price ($50) and the number of tablets may be off putting to some.
