Would 1000cc in each buttocks be enough for a big butt? Or do I need more for the BBL I want?

Thanks for the question. 
In this regard, I recommend you waist and back Liposculpture, getting better curves especially in the waist, improving your body contour.
Finally, I suggested take the fat we get and transfer to the buttocks and hips, to mold them and get better volume, contour and butt projection, is that we know as "Brazilian Butt Lift" (BBL).Kind regards

Thanks for your question. The amount of fat transferred during a BBL depends on the quantity available and the extent of buttock augmentation each patient desires.  Sufficient body fat for a buttock augmentation is very patient-specific, depending on an individual’s body shape and proportions as well as their expectations.  
Buttock augmentation with fat grafting is one of our most popular procedures in Colombia, and from experience we can tell you that some patients do very well with 300 cc of fat per side while others can need 800 cc or more.  That said, you definitely have to choose your surgeon correctly and make sure that he/she has the training and experience to meet your goals with absolute safety.  Best is a Board Certified Plastic Surgeon with specialized expertise in this procedure.

Without an in-office consultation, I am unable to specifically state whether you could achieve your desired results. I frequently liposuction 5 liters and transfer 1000 cc to 2000 cc per buttock, but this amount can be fine tuned based upon patient desires and expectations.  Upon patient request, I frequently add fat to the buttocks and the hips at the same time.
I perform about 500 BBLs each year, and this procedure is the most surgeon dependent plastic surgery procedure. Find a plastic surgeon with ELITE (experience, board certified, education, favorable patient reviews) credentials who performs hundreds of BBLs each year. Then look at the plastic surgeon's website before and after photo galleries to get a sense of who can deliver the results you are seeking.

Dear Compassionate1903,
based on your photos, you look like a good candidate for a BBL and TT. Liposuction of your abdomen, back and flanks should give you more curves and hourglass shape and fat transfer to buttocks should give you more projection. Full tummy tuck should tighten your abdominal muscles and remove the excess skin. 1000 cc of fat should provide significant increase in size. I would suggest you to consult a board-certified plastic surgeon because only after a thorough examination you will get more information and recommendations.
