I really suggest you buy it, not an advertisement. My personal experience is really good. I am a mountaineer, but my joints have been uncomfortable since I came back from Mount Tai last time. Fortunately, I found it in time. I really feel better after eating the green bottle of move free bought by my wife. I thought IQ tax at first, but now I don't have to worry. I can take the initiative to eat. I have emptied a few bottles. I ordered a lot for my wife. After all, my joints should be prevented early, otherwise no one can save you when it is really serious!
