There is but one way to heaven and that's through God's Son Jesus Christ. He's the one that paid and died for our sins, no one else. It clearly states in the Bible "that if you confess with your mouth, "Jesus is Lord," and believe in your heart that God raised him from the dead, you will be saved. For it is with your heart that you believe and are justified, and it is with your mouth that you confess and are saved."
Now that does not say you have to be perfect or that by works you are saved. It's by Grace, a gift, that we are given this opportunity for salvation. Nothing else.
So, unless using anabolic steroids prevents you from accepting Christ then you have nothing to worry about.
The real question is will you accept Christ? Now that's a question.
