that would be up to the endocrinologist but most people by the age of 18 have reached their adult height. hgh will not help if your growth plates have closed (you need an x-ray to make that determination). this issue is best handled by a specialist -- an endocrinologist.
i am 18 and my height is just 164 cm. help! . when i visited my the doc when i was 16 after getting all the hormones checked she suggested that i could go for hgh injections but i didn't go with that because it was costly an i believed that i still had time to grow. now i'm 18 and my height is 164 cm. do you think i could still go for that treatment since it was more than 2 years ago? will it be effective now?
