If roids doesn't get you, modern additives will. You are pumping your muscles but what about your body organs? If it works too hard, it may fail you.
If you want to get technical, chew on this. Milk from a cow is what we drink or feed our kids. Cow milk is for calf. It pumps them up to be big and giant. Now imagine that. We are drinking something that is like roids and supersize us.
What about chicken? They pump fed chicken for 2 months to look like they are at 9 months. The faster they grow, the faster they can sell it. We are eating something that is like roids there too.
