Most will have heard of ‘Performance Enhancing Drugs’ and how any trace of such found in an athlete will cause that athlete to be disqualified from competing and/or have their race results cancelled.

Basically, these drugs are used for: (a) skeletal growth (specifically oestrogen/imitators) up to the mid-twenty years of age; (b) to boost muscles in strength and mass (testosterone/imitators) and; (c) increase red blood cells for energy conversion capacity.
