I just recently became 18 years old and im afraid my growth plates have closed but im not sure im around 5,8 and its a diabolical expirience, i just found about banded sleeping and im trying it even with the risks i dont care i hope i can reach 1-2 inches in few months, i just hope my plates arent closed. My father says he grew at 19 (about 4inches) so i hope i am a later bloomer too (cope)
