Did anyone in here actualy surpased their genetic potential using HGH?

My brother is 5'10" and went through puberty at everybodys pace. I'm 15, 5'7", and I'm a late bloomer. I'm wondering whether starting HGH now could help me end up taller than my brother, or at least accelerate my growth so I can be the same height as people my age.
