Buying these pills will only reduce your wallet size

There's no medical way of reducing breast size through pills. I would caution you to stay away from mesotherapy or lipodissolve to reduce the fat in the breasts. Depending on your age, a young woman has a lot of thick breast tissue and not a lot of fat in her breasts. Surgery is the only well established way to reduce your breast size. In my practice I use a short scar breast reduction technique which avoids placing scars under the breasts. These tend to show in the cleavage and lateral chest wall area which can limit you in your choice of clothing and swimwear. Seek the advise of a board certified plastic surgeon who has a lot of experience in breast surgery.
