Accept your height: If you went through puberty and have the features of an adult male, you likely stopped growing at 17-19 like most males.An x-ray of your wrist.hand could show potential for more growth, but that would be matched by relative immaturity of other features. If your growth centers ore still open, a balanced diet, proper rest and exercise support maximum height.
