What's the allowable amount of fat cc's that can be harvest & injected for bbl?

5 liters of lipoaspirate is the upper limit in an outpatient setting in most states.  The restriction in fat transfer is only restricted in the sense that the amount harvested is restricted.Try to research this to find the surgeon who consistently produces the
results you would expect. Look at reviews on this site and see who gets the surgery right every time. Find
a board certified plastic surgeon who performs hundreds of Brazilian
buttlifts 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. Kenneth Hughes, MDLos Angeles, CA

Every state is different but I usually will suction up to 5 liters of fat in the office setting as recommended by ASPS and ASAPS.
