Can I Take Butt Pills After my Brazilian Butt Lift Surgery to Enlarge the Size?

Sorry to hear that you are unhappy with your Brazilian Butt Lift. 
There are many factors that play a part in determining how much fat can be injected, as well as many factors that effect how much fat will survive and many different techniques used by surgeons performing this procedure. 
At this point, you can take any pills that you want, but I guarantee that there is no pill in this world that will specifically make your butt bigger!  Don't waste your money!

Hi there-

Unfortunately there are no safe and effective options for non-surgical enlargement of the buttocks.

Your best bet is to openly and respectfully discuss your disappointment in your outcome with your surgeon. If you used a Board Certified Plastic Surgeon, I am confident that he wants you to be happy- you may have good options for  more closely approximating your goals.

We can't predict how much will be injected with exact precision but it does get very close as you do more and more of these surgeries.  It seems to me that with bodyjet I've been able to inject more and more of the suctioned fat.

I don't know if any pill that will help an insufficient fat graft result, not yet.  If there was one, we'd be very well aware if it.  Give your result some time before taking any drastic measures and see exactly what it looks like.  With this you can see what options you have.
