Human growth hormone supplementation "buys" height

Allegedly, wealthy parents give their boys naturally secreted human growth hormone ($30-50/mg for Omnitrope/Genotropin), 0.16-0.24mg/kg from age 11-16. For $100k-200k, you add 5 inches to projected height in 7yrs! Maybe it's possible to BUY height.
