A friend of mine who used to be a muscular guy, eventually just stopped goin to the gym and it went all to fat basically.. He was 50+ lbs overweight a few months ago. He started going back and was trying to lose weight before he hit the weights hard again.. Well he lost these 50lbs and now has alot of loose skin.. Is there anything he can do to aid in this xtra loose skin other than surgery? Is there a supplement etc? Im sure it will get a bit better when he puts on more muscle mass, but he is cannot be as large as he was at his fattest.
