First of all, I don't advise you to take medicine for breast enhancement. After all, that kind of thing is not natural, and at your age of development, eating too much is definitely not good. Also, I don't think you need to worry. Development varies from person to person. You can ask your mother if she is developing well at your age. If not, you don't have to worry, maybe you are developing late. If there is, you can use massage. Go to the store to buy massage oil to massage your chest every day. It takes about ten to fifteen minutes to massage clockwise and counterclockwise. This will be very effective. I suggest you don't worry, after all, there are a few people who are well developed at the age of fifteen.

Weight loss:

Your height and weight are a little overweight, but you are at a developing age. If you want breast enhancement, I advise you not to lose weight. Because weight loss can be reduced at any age, and the development of the chest is in recent years, you'd better let the chest develop before losing weight. And if you lose weight now, it will affect your height. Strengthen physical exercise and lengthen your muscle lines at ordinary times, and you will naturally look slim. After all, you are still young, and it is easy to lose weight when you are eighteen or nineteen.
