Can You Tell Me About Human Growth Hormones. I Have

Can you tell me about human growth hormones. I have seen them advertised on TV. These drugs or drug is supposed to give you more strength, more energy and a better over all feeling about yourself. Results are supposed to fight depression and give you a better feeling about yourself and your family situation. They are costly but if they would help my husband to feel better about himself since he can't do so many things that he used to do, i.e. do some of the yard work, helping me in our home, running errands. He just sits in front of the TV all day.. no exercise, etc. Some days he has no appetite at all. Frankly, I could use some more energy myself since I have to see to so many things he says he can no longer do. I really need some answers re: are they safe, do you get what you pay for? Do they help with depression??? Thank you.
