And, yes, it’s aggravating. I work out a lot and have heard the whispered “steroids” bs for 30 years. No, I work out hard, eat right, and am not a pussy. I suppose it should be a compliment, though.
Your link goes to a study that is limited to body builders in one city in IRAN. It does not reflect the universe of body builders. Although I have never been a body builder (I was a power lifter), I see a lot of body builders at the gym, and the tell-tale signs of steroid use are epidemic.
