Dear, I would NOT recommend taking any growth hormones for this. I would just say accept this.....you are a petite woman.
Growth hormones are not safe unless they come from a licensed doctor. If you were thinking about finding them elsewhere you could kill yourself. I, too am vertically challenged, but its better to accept who you are then to harm yourself with something that will not work. Try high heels. Not much for your size? There are place to have custom shoes made, I had a great aunt who was a sz 3 and she was not confined to kids shoes.
