Hi,i'm 15 years old boy. I'm 5'5 high now,is there any chance to reach 6'6 by 25.i'm 55 kg,is that normal for my age. Are there any medicines that can boost up my height. some of my friends are 5'8,5'9 high though they are of same age,i even hesitate to walk beside them as i am short compare to them,i want to catch up with them. So, please help me
