April is when baseball season gets into full swing. Edwin Diaz tore his patellar tendon last month in the World Baseball classic. This is a classic HGH-related injury. HGH grows muscles, but does not grow tendons. The muscles in the legs hypertrophy putting more strain on tendons. In Edwin Diaz's case he completely tore his patellar tendon which rarely happens to mere mortals.
HGH has been used by baseball player since the 1990s and also causes enlarged foreheads. Unfortunately, HGH being a growth factor increases the incidence of colon cancer.
