Growth hormone works even if you are genetical short (familial short stature). Definitely works for many children.
Regardless, kal el is correct. There is almost a 0% chance you are not done growing. The people that tend to grow past 17 are white, tall, not asians, unfortunately.
Genetics is weird. Plenty of same-sxx siblings with 3 inch differences. Growing up in same conditions. At the end of the day some kids inherit "more" of their moms side, some inherit more of their dads side. It is what it is, unfair sure, but nothing is fair or makes sense in life.
