6'2" at 16?
Wow, I will never see that.
How can you get bigger than that at 16?
You will grow for a couple of more years anyway.
You are producing massive amounts of HGH and hormones right now. Just lift heavy and eat alot, dont worry, you will grow whether you want to or not.
Dont fall for that scam above.
You are too young anyway to mess with that stuff.
A good diet will do the same or better anyway (if it was legit), and better for sure if it is a scam
