As a bodybuilder, I see quite a few patients who want some form of implant enlargement for a particular lagging muscle group. The placement of pectoral implants usually involves customizing existing implants to fit the contours of each patient to produce a natural look that fits chest wall and pectoralis dimensions. Pectoral implants are usually placed through an incision under the armpit in about a one to two hour long procedure. I typically charge between $6000 and $10000 depending upon the relative difficulty of the operation and the estimated time in the OR.
