allot of people i know actually started juicing at age 19 and for some reason grew 1 inch to 1.5 inches, 1 guy at the gym, grew 1.5 inches from 5'10 to almost 6'0. with his shoes on, hes over 6.......but he had an x-ray done now and they say his epiphysical cartilage has fused, so no further growth at 19, but wow that was some impressive height he gained, wtf. ????? if he waited he might have gone to 6'1 or more, but he wants to compete and 6'1 is too tall for him...
