Id like as big silicone buttock implants as possible. would it be possible to get 1000cc? 3 operations to get there? 350cc, then 700cc, then 1000cc? is 1000cc the biggest for buttock silicone implants? or can one customize bigger? would i have to get it over the muscle? would it work even though one is considered thin, to get big implants over the buttock mucsle? thanks
