AN top dogs, known well for their HGH Up. Have one of the top joint supplements out today. Animal Flex would be the only other complex formulated product for joints. Some rock the glucosamine, msm, chondrointin combinations. AN have a little bad boy called, Osteo-Sport. Not only featuring solidly researched joint ingredients but some of their very own heavily studied contents. A well named brand and a product you can count on being legal for all countries. Nothing legally damaging, especially when it comes to helping you joints.
