Where it comes from: Branched-chain amino acids are essential amino acids (specifically, valine, leucine and isoleucine). They are essential, meaning we must get them in our diet because our bodies do not produce them, explains Sarah Currie, RD and personal trainer for New York City-based Physical Equilibrium LLC.
At what age do boys stop growing? The stopping date for male growth is just as variable as the starting date. Some men are done growing around the end of high school, while others continue into the college years. Puberty generally lasts two to five years, stopping around ages 17 to 19 for boys. At the end of puberty, the growth plates on the long bones close, which ends the normal period of growth, says Dr. Gettleman.
So, the most appropriate answer to questions like âwhat age do boys stop growingâ or âwhen do guys stop growingâ would be 18. However, there are a few cases where men continue to grow till 21 as well while there can be the odd exceptional case where a man might continue to grow till 25.
