I've been on Osta for 3 weeks and 2 weeks ago I've started to have some pain on my right knee. Pain is very bearable (4/10) but its been very irritating. I've read that Osta was shown to help joints/joint density so I dont think that may be the reason why. I was wondering if I should just take a break from doing legs a bit? Or continue and get some Flex RX? Thanks
