Human growth hormone is the only thing that you could take to increase your height beyond it's genetic potential, which is clearly out of the question. Though you should try to get as much sleep as you can as the brain does release human growth hormone after 2 hours of sleeping. Which is probably why I'm such a runt as I rarely got more than 6 hours sleep a night during most of my teens.
Dude, I was 5'9'' when I was sixteen, too. Guess what? I'm 23 and I'm still 5'9''. But if I'd only eaten me spinach, I'd be the white Shaq.
I am 6'3, when I was 16 I was probably one of the shortest guess in the whole year. Don't give up hope. Keep drowning yourself in milk. :deal
As long as you eat healthy and in sufficient amount and don't do excessive weight lifting you will grow to your genetic determined height.
You're 4ft 9in tall? Bwahahahaha You should join this lot: This content is protected On a serious note, there is about a 0.0001 percent chance you'll grow to be 6ft 3in in the next three or four years. Unless you develop some sort of freak tumour on your pituitary gland or something like that, I doubt you'll make it over 5ft 7in. And you'll only reach that with a bit of luck.
