I'm not sure how to even reply to this. I mean you're entitled to your opinion, but it seems strange for someone who frequents the Anabolics section so much. So you're telling me that you think Anadrol is better used when in a caloric deficit? Point is, yeah (SOME) people can put on muscle with enough calories and the right training. But who wants to wait 3 years to put on 10lbs. of quality when Summer just around the corner LOL. Ok, that was sarcasm. But most people who bulk naturally also put on way more fat than someone who is on gear. Me included. Your statement is merely an opinion and not based on facts at all. Other than AAS are used to prevent muscle wasting in people with disease, etc.
AAS help you grow, maintain, cut, gain strength and performance. Don't give all the credit to just muscle size. They are PED's. Performance enhancers. Who gets strong in a big deficit? With the aid of steroids some do, but nothing like eating a ton, lifting a ton, and taking a cycle.
I trained naturally for over 10 years. And while yeah, I got a touch of vascularity and changed my composition and put on a few lbs. of muscle. First big AAS cycle and I gained 30 pounds of mass in a good surplus. And lost body fat!!!!
I'm not trying to promote, "hey everybody do steroids", I'm just saying the idea that they are most useful on a cut is a bit silly.
