Hi. I've had over the muscle 750cc HP for like 10 years (competed in bodybuilding/figure) and decided to go under the muscle 4smaller since I was having back issues. I bottomed out not even a year after my surgery. My surgeon convinced me that he could fix it with redoing the pockets and doing a durasorb internal bra. I trusted him and the same thing happened in less than 1 year I'm bottoming out.
