Hi. Have you been disappointed with glucosamine supplements? Please email me for important information that you should know: amcq365@***.com. Several medical studies indicate that glucosamine does not promote cartliage regeneration -- as often claimed. There's a class action lawsuit against the glucosamine brand 21st Century Healthcare. If you took 21stCentury-brand glucosamine/chondroitin, are unhappy with the results, and feel you were misled by advertising or claims about the product, please reach out to me. I can provide information about this class action lawsuit and put you in touch with attorneys who are handling this case. Thank you.
