Can I grow any longer?
I am 16 years old. My parents' heights are about 5'5" and 5'0" and my sister is 5'1". I had my knee's and hand's X-ray and both of them are fused. Since then I have grown only an inch or two. I was 5'1" back then now I am like 5'3" or 5'4" in morning. I have been taking Vitamin D supplements along with Vitamin A, Zinc, and Magnesium. Doing yoga on regular basis and body weight exercises like push-ups, chin-ups, pull-ups, and dips. I have been sprinting and skipping rope and my diet is full of protein (junk food only on Sunday).I do not know how I stunted my growth. Maybe late night cravings with junk food and also bad sleeping habits might have contributed to my short stature.
I have heard men do not stop growing until the age of 21 or 25. When I compare my legs to my friends we have the same length, maybe an inch or two difference but they are like 5'10" or 5'11". I have hairs on my legs from a year an a half. I have little facial hair (not too much). My genitals are not fully grown but I have pubic hairs. I want to be at least 5'7" or 5'8". Since taking HGH will not affect my legs (growth plates ossified) but will it affect my spine? I feel like my torso is very short compared to my dad too. If I can get prescription for HGH, will taking it lengthen my spine or harden the long bones which will result in growth (2 to 3 inches)? I have been looking for answers online but I found none relating to spine growth from HGH. As far as I have seen in gigantism most of their height comes from their torso. If I take HGH will my spine grow like theirs too? Since I am only 16 and not fully matured. I do not want to do the leg lengthening surgery (will affect my athletic performance) and also I forgot to mention I have never got a growth spurt in my life. All my height growth has been gradual. When I looked at my friends after a long summer they shot up to 4 to 5 inches. Whereas I stayed the same. Please tell me if I can do anything regarding my height.
