“I have been using this product for a few weeks. I suffer from knee pains after heavy training, running etc. I am sceptical of fast fix products but this one works for me. Since using Flex joint pain has reduced and recovery is a lot easier.”
“Was having significant knee pain in each knee, nothing OTC helped, was daily 24/7. After 2-3 weeks of Flex all pain is gone! Love this product! I do not have arthritis so tried this product.”
“When I first started taking Flex, it helped ease and reduce the back pain I was having. I still take it to moderate any discomfort I occasionally have. It has really helped.”
