What are the best breast enhancement pills, creams?

NONE! None of these creams, pills, or "bio-identical" hormones do anything but enhance the wallet of the seller. If anything worked, trust me, we all would know about it. Though I am a plastic surgeon, i would be just fine even if the most common operation i perform (breast enlargement) "went away." I do lots of other good operations as well. If you want larger breasts, get implants.
Snake Oil. Granted I have a vested interest in ongoing breast implant surgery there are no creams and pills that can do what implants do, as imperfect as the devices may be. I suggest if you don't want implants to save your money at this time.
