Laolaishou is a company that sells health products. It's not a lie over there Aminoglycan is a kind of thing that can protect bones and joints, but you should not confuse it with medicine. Compared with drugs, it takes effect slowly and is a health food that can be taken for a long time, but it has the advantage of no side effects. Health care products are expensive and can be bought if family conditions permit. If your family conditions are average, wait and see. It's no use eating health care products for only three or two days.
