Hormone injections do not necessarily make the body taller. There are many different types of hormones, all of which have different effects, including hormones for immune system diseases and hormones for short stature. The prerequisite is that the endogenous growth hormone is not sufficient, so that the use of exogenous growth hormone can play a role in height growth, otherwise it is not very meaningful. And most importantly, when using growth hormone to promote height growth, it is important to make sure that the epiphysis is not closed. If the epiphysis is completely closed, it is meaningless to use growth hormone even if it is used again.
