Hi, I'm A Male 14 1/2, I Am Currently 5'7"

Hi, I'm a male 14 1/2, I am currently 5'7" but my absolute minimum height that I could accept would be 6' even my dream height would be 6'4" but that seems unreal. My mom is 5'4" My dad is 5'10" my moms side is a bit taller my grampa and uncles are all 5'11" -6'3". So I really want to keep growing and reach my goal is there anything I could do at home or any natural ways to boost HgH? I've heard of growth supplements specificaly "Peak Height" and "Growth Factor" plus and financially they aren't really a problem but are there down sides to any these, becuase my mom and I have agreed to consult our family doctor for further information and are ready to consider these an option if don't reach 5'9" by my birthday in march. I am very athletic, my diet could use improvment, I come from Italian and Mexican descent. Thank you.
