International Natural Bodybuilding Association plans to store samples for eight years.

ASADA have the capability to store selected urine and blood samples from INBA competitors in their deep-freeze facility, called the Tank, for up to eight years. With this capability, we can retrospectively analyse samples using advances in testing technology to detect prohibited substances (such as human growth hormone) and methods, and enforce sanctions against athletes who return a positive test. The Tank is at the National Measurement Institute, a WADA-accredited laboratory. INBA can serve sanctions up to eight years after the competitor has competed.
