Tweettrust me bro, a junior in high school is not done growing in height, Yes you may have done the majority of your growing and you will not have any growth spurts, but you will still grow another inch or two or in rare cases more, until you are 25. if you use AS you will close your growth plates and remain the height you are forever. You may not care now, but 10 years down the road you may be kicking your own ass for it.
