What kind of estrogen supplements make your butt and boobs bigger?

Save your money. There are thousands of supplements advertised to do all sorts of magical remedies. Very few supplements have real research studies to show benefits (but manufacturers make claims, based on theories, animal tests, testimonials, chemical similarities, etc...). If a person took enough estrogen-containing supplements to enlarge the breasts, just think of the cancer risks of such an estrogen effect.
Birth control. Some women report experiencing an increase in breast size and weight gain with birth control pills. These side effects do not occur in all women. Because you are over the age of 35, you are at increased risk for other side effects, including blood clots. If you are seeking increased breast size and buttock augmentation, your best bet is to see a board certified plastic surgeon.
