I just bought Bustmaxx pills. Can I take pueraria mirifica pills with it too?

Pills that purport to make your breasts larger are unsafe, uncontrolled medications derived from plant materials.  They are not a good alternative to breast augmentation and can be dangerous.

There are no pills, lotions or potions that will increase your breast size noticeably. However there are surgical options that include using an implant or your own fat to enhance your breast size. For your question specifically you should contact the manufacturer or a pharmacist. 

You should have saved your money. They don't work. As the FDA does not regulate these substances, we don't even know if they are safe!
