I took steroids in the off season to get stronger.
Is that allowed? Why would you take steroids in the off season to get stronger?
They work very well to build muscle and give me a competitive edge.
Using steroids to build muscle is very dangerous for your health. They may give you an edge but they can cause serious health complications now and in the future for you. The risk is not work the reward.
I've never witnessed any debilitating effects and neither have my friends that also take them.
That's interesting, but I think the negative effects are more long-term. You might not even realize there are problems for years. I think you should talk to a doctor about your steroid use and get some professional advice.
