How long should I work out to gain muscle mass?

The answer to this question is highly individual and depends on numerous factors including age, genetics, diet, etc.

However, a good rule of thumb is that you should be working out for at least an hour each time if your goal is to gain muscle mass. And it’s important to note that steroids and other performance-enhancing drugs can help you achieve this goal much more quickly than working out alone.

That being said, there’s no substitute for hard work and dedication when it comes to achieving the body you’ve always wanted. So make sure you’re putting in the effort in the gym and eating a healthy diet full of protein and complex carbohydrates. And remember that patience is key – results won’t happen overnight, but with time
