More than likely someone has made fun of your height (Probably a chick) for you to really want to be taller. I know you really want to be taller but like these guys said no need in stressing about things you can’t control. Most people stop growing around 21 years old. Maybe go to the Dr. and get your testosterone checked. I’ve heard of some people that for whatever reason hit their growth spurt late. I’m not sure if it was into their 20’s but maybe a teenager who took medication that suppressed testosterone during the growing years would the bones still be fully developed? I was a late bloomer and I was 5’4” when I graduated high school and didn’t hit my growth spurt until my first year of college (age 19) when I did my first cycle. I am now 6’1. But I’ve always been under the impression height is more less preprogrammed in your genes. I hope everything works out for you “Guesswhat”. Just be happy for who you are and everything else will fall into place.
