It's impossible. Secondary development is not that simple. If so, we can find it earlier. Now under normal circumstances, bones stop developing at the age of 18 to 23, which is determined by human genes.

Height refers to the vertical distance from the vertex (V) to the ground. Generally in centimeters, commonly used as "meters". Height is the length of the longitudinal part of the human body, which originates from the longitudinal growth of the human body and is greatly influenced by genetic factors. The height development of girls is earlier than that of boys, and the rapid growth period is from 12 to 13 years old, and the growth stops at 19-23 years old.

Boys' height develops late, growing rapidly at 15- 16 years old and stopping growing at 20-25 years old. The long bones and vertebrae of the limbs have ossified and their height has stopped growing. There are many factors affecting height, such as heredity, nutrition, sports, environment, living habits, race, endocrine, sexual maturity, distant marriage, medical progress and so on.

I advise you not to believe these things and not to buy them. On the contrary, they are harmful to your health. I don't want to believe in any product that an adult can sell. This truth should be understood. If the topic is the stage of growth and development, if you want to increase your height, you should strengthen your nutrition intake, increase physical exercise, go to bed early and get up early, and develop good work and rest habits, which may make you taller.

Correct method:

1. It is suggested to increase nutrition, eat more, exercise more, and do more stretching exercises to make the body look stronger, instead of being thin and weak, with wider shoulders and stronger body. People will look taller and have a good figure.

The height can't be changed any more. It can only be disguised by some external heightening, such as wearing some heightening shoes such as old shoes. It is not difficult to increase 3~4cm. For example, the old shoes I often like to wear are comfortable and high, and I like them very much.

3. You can also wear something like heightening insoles to increase your height, which can be used occasionally at parties and blind dates.
