Premise: Alex Rodriguez . In February 2009 , after previously denying use of performance-enhancing drugs , including during a 2007 interview with Katie Couric on 60 Minutes , Rodriguez admitted to using steroids , saying he used them from 2001 to 2003 when playing for Rangers due to `` an enormous amount of pressure '' to perform . Growth hormone ( GH ) , also known as somatotropin ( or as human growth hormone [ hGH or HGH ] in its human form ) , is a peptide hormone that stimulates growth , cell reproduction , and cell regeneration in humans and other animals .
