once the growth plates have closed/fused you will not grow any taller and there are no supplements or amino acids that can cause growth plates to reopen again or change your height. please don't waste your money on false claims. if you have a lot of money. and i mean a lot of money a person can undergo painful orthopedic surgery of the legs to make them longer. this procedure can had inches to your height but it is not without risk. sometimes we just have to learn to accept who we are. some people are born with disfiguring birth defects some without the ability to walk or see or hear. your only issue is that you are just seven or eight inches shorter than the average man. as a matter of fact you are only two inches shorter than my brother and step-father. in the long run this is not a disability. a man is judged not by how tall he is but who he is as a man.
i'm 20 years old and only 4'9'' how can i increase my height. and is there any way to reopen growth plates. some suggested me to take l-arginine with l-ornithine so is it safe to take this if yes then please guide me
