Adults cannot grow taller with growth hormone.
Human height depends on the growth of bones. The growth point of bone growth is located in the epiphysis, where osteoblasts continue to produce new bone cells to grow bones.
Only until the epiphyses close before adolescence is the body able to grow in height. Once the epiphyses are completely closed in adulthood, a white line is formed and the basis for growth is lost. Therefore, for adults, it is not possible to continue to grow in height with the current technology.
If you want to grow taller, you need to pay attention to balanced nutrition before the adolescent stage, puberty development stage, to do meat and vegetables, appropriate participation in physical exercise and adequate sleep, in order to promote the growth of height.
