There is no simple answer to your question. I would not recommend having anything injected into your buttocks other than your own fat through a procedure commonly referred to as the Brazilian buttock lift. This procedure involves performing liposuction on area of the body to remove excess, unwanted fat and transfer it to the buttocks. The prices will vary by region and surgeon. Your best bet is to find a board certified plastic surgeon and go for a consultation.

This all depends on the surgeon, city, surgical facility, technique and several other factors. In Toronto, Ontario, you can expect to pay around $8000-$9500 for butt augmentation with fat injections (Brazilian Butt Lift).
Buttock Augmentation with Fat Transfer
Transferring your own fat to the buttocks is a very popular way to improve the size and shape of your buttocks through injections (and without artificial implants). In addition, there is the added benefit of improved contour to the body due to liposuction of the area the fat is harvested from. Lastly, there are significantly less complications associated with this type of augmentation versus augmentation with implants. Since every patient is different there is no way to provide you with an appropriate price quote. The price would depend on the amount of surgical time required to achieve your desired results as well as the amount of fat that would have to be transferred.
