Drugs will allow you, at smaller sizes, to get ripped with very little effort. Drugs will allow you, with extreme effort, to look like the rock. Many actors that get lean for roles could possibly be natty, though I'd say few have the work ethic. Nobody natty is as big as the rock. It's not possible.

Not to mention the idea of actors putting on 10-20 pounds of lean muscle in, say, 3-6 months between movies is laughable (but remotely possible) in their 20s. When you see guys doing it in their 40s you have to be actively lying to yourself to believe that possible.

Oh, and low doses of much of this stuff, under careful supervision of a doctor, makes you healthier. Your skin will be better, you'll look younger, you'll have (slightly) more muscle, etc. Aging clinics are greenwashing drugs: you pay $2k/mo and get scrips making everything nice and legal.

Actors routinely sport lean muscle mass that is unrealistic without 'roids.

Presumably millions of people think Christian Bale, Daniel Craig, and Chris Pratt, and many, many others have been natty in recent roles. Laughably false. Look at models and actors from the 50s and 60s and note their ages to have an idea what is realistic.
