I used to hate my "fat cheeks" as I used to call them in my complaints. T has definitely slimmed my face down, as the other guys have said, there was a stage where my face went puffier and more full lookin. Now however, at 13months on T, my face is more masculine looking and is less "fat" and round, more angular.
I never thought my face would change drastically, but its change to where I pass 100% now, so theres always hope :p
