“Not sure of efficacy. I can say that unlike other joint supplements I've tried, Flex doesn't have side effects. I've been taking Flex almost a month now, and my knee feels somewhat better, but the change has been too gradual to say it's Flex (vs season change, et al) that is effecting the change. Plus, I still have days when the knee pain spikes for no apparent reason. Seems this would not happen if Flex was making systemic change in my joints.”
“I had been on flex for 5 days when I noticed the dull ache in my lower back that is always there was much better and a few more days I didn’t hardly notice it. I’m sure continued use of flex and I’ll be my young self again. I hit a large bucket of golf balls without any pain in my back. Thx to flex I can play again.”
“I personally have received very little to no benefit from from Flex. I purchased this supplement for relief from hip and knee pain. After several months, I don't feel any difference. Will continue to take the remainder of my order but will not purchase again. Customer service is very good. They return emails quickly and answer all your questions.”
“I was skeptical. I tried it for a couple weeks snd am very pleased. Have tried therapy, meds, IMac regeneration and nothing else has eased my pain. Going to be a longtime customer. I recommend this to anyone.”
