subject: Understanding HGH Effects on Athletes [print this page] It has been assumed by many that HGH is able to help the body recover from injury. Both theoretical and practical evidence has been shown to support this theory. One example can be found with athlete Abdul-Karim al-Jabbar, a Miami Dolphin football player. One of this athletes knees seemed to be destroyed, until he turned to HGH. He had previously undergone multiple surgeries trying to repair his knee, but after taking HGH, his knee began to recover. Before he started injecting HGH almost all of the cartilage in his knee was gone, and after he started the injections his knee began to heal. This is only one example that shows HGH effects on athletes.
