Murphy admitted that he was forced to resort to taking the performance enhancing drug while recording track 'Dance Yrself Clean' as his voice began to deteriorate in the final stages of making the album.
He told NME: "It was [the] last song I finished, I lost my voice trying to do it. It's the highest register I've ever sung in.
"I had to sing it with a voice that was completely blown out, but then I took lots of steroids! So I juiced for this record! It's cheating, I'm cheating! I cheated to sing this song."
LCD Soundsytem recently announced that their third record This Is Happening will be their last.
