What is the fastest way to increase your height in puberty?

Asking for someone else? At a listed age of 22 you are past puberty and done growing. During puberty, adequate restorative sleep, good nutrition and exercise allow you to attain maximum height. An x-ray of the wrist/hand can be evaluated for open growth centers. When these are closed, no more linear growth will be possible. There are no supplements/meds/exercises that can add height at that point
