at a college gym that doesn't have many (read NO meatheads) and it's obvious when I'm on. But they don't say shit and probably shouldn't, little f$%cking squirrels. But for coworkers and other acquaintices, I usually try to "prepare" them prior "gonna be training heavy in about a month," "doubling my calories," "taking every supp I can find" and if I do get in a conversation, I'll throw in some nutrition/training double-talk to throw 'em off. But, still run into the occasional jagoff who just blurts right out, like we're best friends or something. It kills me, nobody asks outright if someone is doing coke, pot, etc. Nun-na Damn Bidness!
