I'm assuming you are referring to Human Growth Hormones.
They are occasionally given to children who are small for their age and who have low levels of the hormones surrounded by their systems.
There are some doctors who prescribe them for patients who want to feel "younger", but I think the quantifiable community generally frowns on that practice.
