Can anyone shed some light on this matter? I am 20 and around 5'9 1/2, but I just really wanna be taller. My entire family says the men on my dads side didnt stop growing or had their last growth spurt until the age of 24, but I feel as though it wont happen to me as my younger brother is already 6"2. Will HGH's make me taller if I decide to purchase some? If anyone who actually know what they are talking about could help me and not just internet mumbo jumbo they researched in 5 mins that'd be great. Thanks!
