Wow, i think it seems like either way, u didnt have enough time to drink the certo and fluid before the test. U said u took it around 1-1.5 hrs before the test? Though ur piss was clear, it apparently was not enough fluid for dilution to work. Certo is cook with dilution as a back up plan. The omni cleansing softgel contains some creatine, which would help with dilution.
