The FDA has stated that no such products have been shown to work. A better tactic would be to reduce your body fat percentage through good nutrition & excercise.
The most popular brand in the breast reduction pills is the Alexia breast reduction pill. It is 100 % natural food supplement and is affordable when compared with that of plastic surgery. Also it has positive reviews and have not reported any side effects.
Do not use such pills. They may damage your liver or kidneys. If your breasts are too large, go for a cosmetic surgery by a certified Plastic Surgeon only.
Some people say that they work, others say that they don't. The pills use hormones to reduce the size of your breasts so once you stop tking the pills your breasts will go back to the size they are now.
