It seems a candidate for one of the stupidest ideas I have ever heard of to think of intramuscularly injecting something with sodium deoxycholate, a bile acid and detergent which is intended precisely to compromise the structural integrity of (hopefully fat) cells.
Who thought this up anyway? Someone who was at 3% bodyfat and thought it would be really cool to get to 1%?
Beyond this, presumably it is more sensible to worry about the fat, oh, everywhere else, before looking to take out the 'marbling' in your sirloins on your chest, thighs, rump, you name it. So unless you are prepping for a private contest judged by Hannibal Lector, I'd suggest not injecting lipostabil anywhere but into fat deposits.
