S4. Hormone and metabolic modulators
S5. Diuretics and other masking agents
The methods (M) on the Prohibited List are divided into three classes:

All methods on the Prohibited List are prohibited at all times (i.e. both in- and out-of competition).
Alcohol and beta-blockers are prohibited only in particular sports.
