How is this unfortunate?
Injecting silicone can be a lot easier and safer than injecting SEO. The couple of inches that one can gain by daily injecting SEO, with an average of 200 shots(each arm) per cycle, can be achieved with 2-3 visits at the plastic surgeon, which gives you a smaller chance of infection, better results and a one-time procedure.
I'm not saying that injecting SEO/silicone is a great idea, but sometimes it is necessary, specially in competitive bb, that 's why so many people use it.
But after all- that's just my opinion!
