if you have joint problems, go for it.
I have tried to use other less expensive Glucosamine products, and they would be OK, but never fully did the job. I have a bad knee from an auto accident years ago. Now that I'm older and hitting the gym, the knee was bothering me again. This stuff has gotten me about 95% back to normal. I feel great. It took me about half bottle to really feel how well it works. It's worth the little extra, more mid price range over all.
I live in HongKong and got this so quick. there was no delivery fees. Awesome service!!
