I have a history of getting elbow, shoulder, knee, and wrist injuries. After getting diagnosed with a stress fracture in my elbow and a little ligament damage, I decided to look into a joint formula. After reading many other reviews of Animal Flex, I decided to give it a try. Overall, I give it an 8/10. It worked great, but it was just wayyy too many pills to take. After taking Animal Flex a couple days, (whether it was placebo effect or not), my elbow was less stiff, more flexible, and began feeling much better, regardless of the stress fracture. I would recommend Animal Flex to anyone looking for a Joint formula THAT DOES NOT MIND TAKING 8 PILLS. Since being released from the doctor and physical therapist 2 weeks ago, I have ordered Super Cissus Rx, as I'm not looking to take that many pills anymore.
