Hi,
I forgot to add, that you have to keep watching your weight and maintain it under control, again the balanced food and moderate exercise should help you, no soda, no fast food and ofcourse, a double No for aclcohol and drugs.

Hi,
Do not worry, you have still all the time on earth for your organs to grow. Just keep waiting, take balanced food and do moderate exercise, remember food balanced in macro nutrients is the key growth factor at your age, if you want to know the daily requirements of nutrients for your age just refer the link:

Leave the rest to Mother Nature to take care of.
