You're kidding right?
In case you are serious, the answer is no, alcohol does not flush the body of
steroids. That would somehow mean the alcohol would bind to all
steroid molecules and transport them out of the body. But what would happen when alcohol is broken down in the body? It's not excreted as alcohol, so even if it did by some miracle the
steroid molecule would just be released back in the blood b/4 excretion.
