If bodily processes are so strongly governed by hormones that taking cross-sex hormones can trigger essentially a second puberty in post-pubescent people, and people like Andre the giant have their size thanks to an overactive pituitary gland which is what produces growth hormones, why can’t we just inject people with the right hormones to make them taller? Seems like there would be a pretty big market for that.

Children have growth plates in each long bone. A growth plate is an area of soft bone at each end of the long bones that allows the bones to grow longer. The growth plates fuse together by the time a child is 14 to 18 years old. That fusion prevents further length from being added to the bone. So injecting hormones to adults who already have their growth plates fused would do nothing to their height.
