Can you tell me how can anabolic steroids work?

They are hormones: That are similar to hormones the body makes to help increase muscle strength and growth, mainly testosterone and its derivatives. Boys and girls produce about the same amount of these until puberty, when it markedly increases in boys, which is why they have different kinds of muscle development. Synthetic steroids do the same thing, just more so. They also have major toxicity and dangers to health.
