I don't know if this is the right section to post this, I apologize if I'm wrong. Anyway, my younger brother is the smallest in the family. He's 19 and stands 5'4. Our dad is 6 ft tall, our mom is 5'5, and i'm 5'10. He is convinced that there is this site that can help him get 2-3 inches taller. I told him i think it's a scam but he won't listen. So I need your opinion on this. Do you think that these "grow taller" sites/products really work? If not, help me stop my brother from wasting his money.
