It`s so sad when people like that guy try and say they have some new technology and its all lies. When the growth plates "close" (such a bad term) the tissues near the bone end change and calcify, changing their structure. It can not be "reopened". It would be almost the same as saying "turn fat into muscle", they are 2 different tissues. The epiphyseal plate (growth plates) are hyaline cartilage, once mature they turn into bone.
