Metabolic/Endocrine: Decreased glucose tolerance (see PRECAUTIONS ), increased serum levels of low-density lipoproteins and decreased levels of high-density lipoproteins (see PRECAUTIONS , Laboratory Tests ), increased creatine and creatinine excretion, increased serum levels of creatinine phosphokinase (CPK). Reversible changes in liver function tests also occur, including increased Bromsulphalein (BSP) retention and increases in serum bilirubin , glutamic-oxaloacetic transaminase ( SGOT ), and alkaline phosphatase .
Drugs can be added and removed from this list by WADA annually, although not all of the banned substances are explicitly named. Caroline Hatton, PhD , a sports anti-doping science consultant, told in a Mar. 12, 2010 email that "A key concept in prohibited lists is that they avoid being finite. Instead of listing all banned drugs one by one, they list entire drug classes and name drugs merely as examples. This is to keep users who took designer drugs from claiming that they didn't break the rules because the drugs they took weren't listed."
