Deal.
But I would take you to MY IOC LAB - not one you choose to...
They can find traces for 10 years so 1993 is safe - 16 years later... 
Problem is going to be when they find shit load of metabolites you should not have as natural - you will blame contamination of nutritional supplements.
Kyomu - did you check IOC list - you moron?
I will consult about it.
About supps, I havent taken any since May because of my laziness(sometime, i take powder when i want to drink chocolate shake).
The problem is if some substances contains in my foods.
So, why dont we choose only major bbing juicing substances only?
Thats more simple and easy.
