Man, one time 15 cm is too much. In a single surgery you can aim max 10 cm safely. If you want more, you gotta do two surgeries about a month apart and that can get you 14 cm total. But yeah it costs more.
My advice go for 10 cm first, heal strong, then decide if you really want more. Totally worth it if you’re ready to put in the work. Stay focused and disciplined.
