Are steroids administrated by actors?

Steroids are definitively applied by different actors. You may see essential changes in actors’ physique in short period of time. For example, a certain actor has played a role in a film, being quite thin, then, after short period of time he plays a role with increased muscle mass. How can actors increase their muscle size in short time? The answer is self-evident. They use anabolic steroids. But actors deny that they apply performance-enhancing drugs.
Jason Momoa in “Conan the Barbarian”, Chris Hemsworth in “Thor” and Chris Evans in “Captain America: The First Avenger” induced their muscles significantly to play certain roles. Undoubtedly, this aspect led to questions about intake of steroids. But the actors refused to answer the questions connected with administration of medications that possess performance-enhancing effects.
It is known that Jason Momoa induced his muscle size by 30 pounds to play Conan. An actress, Rose McGowan, who also played in “Conan the Barabarian” noticed that Momoa achieved that results not due to steroids. Jason Momoa spoke that he wanted to correspond to a Frank Frazzeta painting without steroid use. It would be ideally, according to the words of this actor. But he mentioned that our world and life were not ideal. Momao said that he had trained hardly. Moreover, this actor followed a strict diet. He consumed broccoli, peanut butter, yams and chicken breast continually.
As for Chris Hemsworth, he increased his muscle mass by 20 pounds in order to play Thor. The actor said that he had eaten a lot. The actor noticed that he had eaten and he seemed as if he were busy with an important thing. Chris Hemsworth noted that it had been quite difficult to eat, when he was not hungry. Moreover, the actor had to eat large amounts of food. According to his words, it was too exhausting.
It is interesting to observe that Hemsworth never lifted weights before playing his role in “Thor”. Couldn’t you find this aspect unreal without steroid use? Nevertheless, he pointed out that he hadn’t used anabolic steroids.
Chris Evens also enhanced muscles essentially to play Steve Rogers in the film “Captain America: The First Avenger”. He claimed that he had enhanced muscles because of trainings and a strict diet.
