The name given to professional drug trialers, who will continuously subject their bodies to experimental concoctions for the betterment of science. Guinea pigging is a dangerous job as there is no way to know if a particular drug will have long lasting and irreversible side effects that could drastically alter your life. Furthermore, most trials will barely pay more than minimum wage.

Most companies will try to screen out guinea piggers, as they will often be enrolled in several trials at one time and will have spent years trying new drugs. This means that their body will probably not react in a normal way during the trials, and the results will be skewed.
