Hello,
Thank you for sharing the information, it is a pleasure for me to answer your question.
It is difficult to evaluate the options without seeing photos,
It is advisable to consult with a certified plastic surgeon, for a good evaluation, to provide you with all the information you need...
Thanks for sharing your photos.Generally fat transfer for buttock augmentation does require large volumes. It is normal to inject 750-1000 cc to each side. A good exam with a board certified plastic surgeon can help you determine how much could be obtained by liposuction.Best of Luck
