What do you say to something like that?
I haven't taken any serious mass gain cycles so I'm not big enough for most people to get suspicious, but I saw a guy in one of my classes get called out today. He's in good shape, but he's got absurdly huge biceps that seem to be growing at an astronomical rate. He walked in and someone just yelled "STEROIDS". He just sat down, started eating a sandwich and let the guy get bored of heckling him.
