How Much Does Testosterone Play Apart?

Testosterone is the number one hormone to build muscle work. However, it's not as significant as people think and I'm a good example of that. The variation from like low average to high average doesn't make a difference. If you ever take an extra testosterone? No, no, because that's performance. Then they're still performance. So what would happen if I started doing it just out of genuine curiosity? I would imagine if I did that there, like how fine it would have.
