Immune System Changes

There is a large amount of data indicating that anabolic steroids may have some effect(s) on modulating the immune system. As with most potential side effects, this is largely dose and compound dependant. There is strong evidence that different analogues produce vastly different effects on the immune system. Testosterone and certain analogues have been shown to be possibly immunosuppressive, while Nandrolone and other steroids are possibly immunostimulating. Both, however, have been found to be beneficial when given to AIDS patients, who clearly have an already compromised immune system. This is because the increase in lean body mass that those steroids can provide is consistent with an enhanced ability to fight off infections, enhanced survival rates, and a better quality of life.
